I have the following raw table structure - a list of credit card transactions:
Date | Description | Debits | Credits
Date will be converted using this approach:
Ensure a valid date inside the cell in Excel
Other columns will stay AS IS. I can create the first row of a target table, but I need to expand it downwards to match the number of rows in the source table.
Is there a way to automate the last part, i.e. row expansion?
I am expecting the raw data table to grow over time, so the target table needs to adjust its row count as well (either fully automated or via a single-click macro).
There is a similar question on StackOverflow, but I am using named tables and named columns:
Matching number of rows in one excel table with the number of rows in another
Table names:
Source : TableRawData
Target : ProcessedData
Date conversion formula I am using in the 1st column:
=MorphDate(TableRawData[#Date])
Paste this code into the worksheet with the source Table (ListObject). I used the Table names you specified. You'll need to adjust the worksheet names to the actual ones in your workbook:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim loSource As Excel.ListObject
Dim loTarget As Excel.ListObject
Dim wb As Excel.Workbook
Set wb = ThisWorkbook
With wb
Set loSource = .Worksheets("Source").ListObjects("TableRawData")
Set loTarget = .Worksheets("Target").ListObjects("ProcessedData")
'Only change Target if Source has more rows or columns, i.e,
'don't shrink, only grow.
If loTarget.Range.Rows.Count < loSource.Range.Rows.Count Or _
loTarget.Range.Columns.Count < loSource.Range.Columns.Count Then
With loTarget
'two kinds of 'Resize in one line!
.Resize (.Range.Cells(1).Resize(loSource.Range.Rows.Count, loSource.Range.Columns.Count))
End With
End If
End With
End Sub
As noted in the comments this triggers if either the number of rows or columns gets bigger. If you want it to change if Target grows or shrinks then change the <'s to <>'s.
If you are interested in the two different Resizes used in the code, and some information on copying Tables, see my this post of mine.

I have two tables in two different worksheets and I want to copy a column from one to another.
The tables can be of different size at but any column I copy from the src table will have a matching header in the destination table.
My understanding is that I have to resize the destination table to have the same number of rows as the source table. But after that I should be able to assign the destination range to equal the source range.
The code below runs with no errors but doesn't do anything as far as I can tell.
Public Sub SyncListObjects()
Dim tblDest As ListObject
Dim tblSrc As ListObject
Dim mappedCol As ClassTrackedCol
Set tblDest = ThisWorkbook.Sheets("Power BI Data").ListObjects("tblDest")
Set tblSrc = ThisWorkbook.Sheets("Imported Data").ListObjects("tblSrc")
'map the matching columns of the tables into a collection
Set destToSrcColMap = CreateTblToTblColMap(tblDest, tblSrc) 'this works correctly
tblDest.DataBodyRange.ClearContents
'the destination table should have the same number of rows as the src
'but keep it's own number of columns in order to be able to copy
tblDest.Resize tblDest.Range.Resize(tblSrc.ListRows.Count, tblDest.ListColumns.Count)
For Each mappedCol In destToSrcColMap
Set test1 = tblSrc.ListColumns(mappedCol.ColName).DataBodyRange 'this resolves correctly
Set test2 = tblDest.ListColumns(mappedCol.ColName).DataBodyRange 'this resolves correctly
tblDest.ListColumns(mappedCol.ColName).DataBodyRange = _
tblSrc.ListColumns(mappedCol.ColName).DataBodyRange 'this runs but doesn't appear to do anything
Next
End Sub
Fixing 2 issues worked for me:
Be explicit about the value transfer:
tblDest.ListColumns(mappedCol.ColName).DataBodyRange.Value = _
tblSrc.ListColumns(mappedCol.ColName).DataBodyRange.Value
ListRows.Count doesn't include the header, so change the following line:
tblDest.Resize tblDest.Range.Resize(tblSrc.ListRows.Count, tblDest.ListColumns.Count)
to
tblDest.Resize tblDest.Range.Resize(tblSrc.Range.Rows.Count, tblDest.ListColumns.Count)
I have 2 tables on 2 separate sheets of an MS Excel 2007 workbook, like below:

Both have the same columns, but they can have different data.
I want to combine the data of both tables vertically i.e. a single table with all the data in a 3rd separate sheet.
If possible, I want to add another column with the sheet name from where the row came.

Can it be done without using macros?
This answer deals with Structured Tables as interpreted by Excel. While the methods could easily be transcribed to raw data matrixes without assigned table structure, the formulas and VBA coding for this solution will be targeted at true structured tables.
Preamble
A third table can maintain the combined data of two tables with some native worksheet formulas but keeping the third table sized correctly as rows are added or deleted to/from the dependent tables will require either manual resizing operations or some VBA that tracks these changes and conforms the third table to suit. I've included options to add both the source table's worksheet name as well as some table maintenance VBA code at the end of this answer.
If all you want is an operational example workbook without all the explanation, skip to the end of this answer for a link to the workbook used to create this procedure.
Sample data tables
I've used the OP's sample data to construct two tables named (by default) Table1 and Table2 on worksheets Sheet1 and Sheet2 respectively. I've intentionally offset them by varying degrees from each worksheet's A1 cell in order to demonstrate a structured table's ability to address either itself or another structured table in a formula as a separate entity regardless of its position on the parent worksheet. The third table will be constructed in a similar manner. These offsets are for demonstration purposes only; they are not required.
Step 1: Build the third table
Build the headers for the third table and select that future header row and at least one row below it to base the Insert ► Tables ► Table command upon.
Your new empty third table on the Sheet3 worksheet should resemble the following.
Step 2: Populate the third table
Start by populating the first cell in the third table's DataBodyRange. In this example, that would be Sheet3!C6. Type or paste the following formula in C6 keeping in mind that it is based on the default table names. If you have changed your tables names, adjust accordingly.
=IFERROR(INDEX(Table1, ROW([#[no.]])-ROW(Table3[#Headers]),COLUMN(A:A)), INDEX(Table2, ROW([#[no.]])-ROW(Table3[#Headers])-ROWS(Table1),COLUMN(A:A)))
The INDEX function first retrieves each available row from Table1. The actual row numbers are derived with the ROW function referencing defined pieces of the structured table together with a little maths. When Table1 runs out of rows, retrieval is passed to a second INDEX function referencing Table2 by the IFERROR function and its sequential rows are retrieved with the ROW and ROWS functions using a bit more maths. The COLUMN function is used as COLUMN(A:A) which is going to retrieve the first column of the referenced table regardless of where it is on the worksheet. This will progress to the second, third, etc. column as the formula is filled right.
Speaking of filling right, fill the formula right to E6. You should have something that approximates the following.
Step 2.5: [optional] Add the source table's parent worksheet name
Grab Table3's sizing handle (indicated by the orange arrow in the sample image below) in the lower right hand corner and drag it right one column to add a new column to the table. Rename the header label to something more appropriate than the default. I've used Sheet as a column label.
While you cannot retrieve the worksheet name of the source table directly, the CELL function can retrieve the fully qualified path, filename and worksheet of any cell in a saved workbook¹ as one of its optional info_types.
Put the following formula into Table3's empty cell in the first row of the new column you have just created.
=TRIM(RIGHT(SUBSTITUTE(CELL("filename", IF((ROW([#[no.]])-ROW(Table3[#Headers]))>ROWS(Table1), Table2, Table1)), CHAR(93), REPT(CHAR(32), 999)), 255))
Complate populating Table3
If you are not planning on finishing this small project with some VBA to maintain Table3's dimensions when rows are added or deleted from either of the two source tables then simply grab Table3's resizing handle and drag down until you have accumulated all of the data from both tables. See the bottom of this answer for a sample image of the expected results.
If you are planning to add some VBA, then skip the full population of Table3 and move on to the next step.
Step 3: Add some VBA to maintain the third table
Full automation of a process that is triggered by changes to a worksheet's data is best handled by the worksheet's Worksheet_Change event macro. Since there are three tables involved, each on their own worksheet, the Workbook_SheetChange event macro is a better method of handling the change events from multiple worksheets.
Open the VBE with Alt+F11. Once you have it open, look for the Project Explorer in the upper left. If it is not visible, then tap Ctrl+R to open it. Locate ThisWorkbook and right-click then choose View Code (or just double-click ThisWorkbook).
Paste the following into the new pane titled something like Book1 - ThisWorkbook (Code).
Option Explicit
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Select Case Sh.Name
Case Sheet1.Name
If Not Intersect(Target, Sheet1.ListObjects("Table1").Range.Offset(1, 0)) Is Nothing Then
On Error GoTo bm_Safe_Exit
Application.EnableEvents = False
Call update_Table3
End If
Case Sheet2.Name
If Not Intersect(Target, Sheet2.ListObjects("Table2").Range.Offset(1, 0)) Is Nothing Then
On Error GoTo bm_Safe_Exit
Application.EnableEvents = False
Call update_Table3
End If
End Select
bm_Safe_Exit:
Application.EnableEvents = True
End Sub
Private Sub update_Table3()
Dim iTBL3rws As Long, rng As Range, rngOLDBDY As Range
iTBL3rws = Sheet1.ListObjects("Table1").DataBodyRange.Rows.Count
iTBL3rws = iTBL3rws + Sheet2.ListObjects("Table2").DataBodyRange.Rows.Count
iTBL3rws = iTBL3rws + Sheet3.ListObjects("Table3").DataBodyRange.Cells(1, 1).Row - _
Sheet3.ListObjects("Table3").Range.Cells(1, 1).Row
With Sheet3.ListObjects("Table3")
Set rngOLDBDY = .DataBodyRange
.Resize .Range.Cells(1, 1).Resize(iTBL3rws, .DataBodyRange.Columns.Count)
If rngOLDBDY.Rows.Count > .DataBodyRange.Rows.Count Then
For Each rng In rngOLDBDY
If Intersect(rng, .DataBodyRange) Is Nothing Then
rng.Clear
End If
Next rng
End If
End With
End Sub
These two routines make extensive use of the Worksheet .CodeName property. A worksheet's CodeName is Sheet1, Sheet2, Sheet3, etc and does not change when a worksheet is renamed. In fact, they are rarely changed by even the more advanced user. They have been used so that you can rename your worksheets without having to modify the code. However, they should be pointing to the correct worksheets now. Modify the code if your tables and worksheets are not the same as given. You can see the individual worksheet codenames in brackets beside their worksheet .Name property in the above image showing the VBE's Project Explorer.
Tap Alt+Q to return to your worksheets. All that is left would be to finish populating Table3 by selecting any cell in Table1 or Table2 and pretending to modify it by tapping F2 then Enter↵. Your results should resemble the following.
If you have followed along all the way to here then you should have a pretty comprehensive collection table that actively combines the data from two source 'child' tables. If you added the VBA as well then maintenance of the third collection table is virtually non-existent.
Renaming the tables
If you choose to rename any or all of the three tables, the worksheet formulas will instantly and automatically reflect the changes. If you have opted to include the Workbook_SheetChange and accompanying helper sub procedure, you will have to go back into the ThisWorkbook code sheet and use Find & Replace to make the appropriate changes.
Sample Workbook
I've made the fully operational example workbook available from my public DropBox.
Table_Collection_w_Sheetname.xlsb
¹ The CELL function can only retrieve the worksheet name of a saved workbook. If a workbook has not been saved then it has no filename and the CELL function will return an empty string when asked for the filename.
You can activate the Office Clipboard (arrow at bottom right of clipboard section on Ribbon Home Tab). Copy both ranges then use the Paste All command as shown below.
You would still need to fill down the sheet name in an extra column first though which can be done by double-clicking the fill handle.
Update
To get the same results with formulas try filling down this for the sheet name:
=IF(ROW()<=COUNTA(Sheet1!A:A),"Sheet1",IF(ROW()<COUNTA(Sheet1:Sheet2!A:A),"Sheet2",""))
and then fill down and across this formula for the values in the tables:
=IF(ROW()<=COUNTA(Sheet1!A:A),Sheet1!A2,IF(ROW()<COUNTA(Sheet1:Sheet2!A:A),INDEX(Sheet2!A:A,ROW()-COUNTA(Sheet1!A:A)+1),""))
lori_m made a really good contribution that I built upon by using Microsoft Excel Tables and structured references.
First make a column in your output table called RowID which contains the row number within the table and then use this to fill the data values.
=IF( INDIRECT("Table3[RowId]")<=ROWS(Table1)
,INDEX(Table1[column1],INDIRECT("Table3[RowId]"))
,INDEX(Table2[Column1],INDIRECT("Table3[RowId]")-ROWS(Table1)))
There is a detailed explanation of how this works on my blog as it was too long to include here.
A slight modification to Jeeped's code.
If you happen to use a similar approach, but with several tables (e.g. more than 10), then it will be rather cumbersome to attempt to manually add every name of every table. This is also a problem if you change names of the tables, since the names are hard-wired in VBA. To avoid additional work, consider this:
So, assume the following:
On each worksheet there is one or several tables, but they have similar structure.
There are only tables on worksheets - no other members of ListObjects collection are being present.
Every time we edit a table on a sheet, this will trigger an update in master table (table 3).
Then the Workbook_SheetChange Sub in the example above could look like the following:
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Dim tbl As ListObject
For Each tbl In ActiveSheet.ListObjects
If Not Intersect(Target, tbl.Range.Offset(1, 0)) Is Nothing Then
On Error GoTo bm_Safe_Exit
Application.EnableEvents = False
Call update_Table
End If
Next tbl
bm_Safe_Exit:
Application.EnableEvents = True
End Sub
Edit. The second routine will then look like:
Private Sub update_Table()
Dim iTBL3rws As Long, rng As Range, rngOLDBDY As Range
Dim tbl As ListObject
Dim sht As Worksheet
iTBL3rws = 0
' consider all tables, excluding master table
For Each sht In ThisWorkbook.Worksheets
For Each tbl In sht.ListObjects
If tbl.Name <> "Table3" Then
iTBL3rws = iTBL3rws + tbl.DataBodyRange.Rows.Count
End If
Next tbl
Next sht
iTBL3rws = iTBL3rws + Sheet3.ListObjects("Table3").DataBodyRange.Cells(1, 1).Row - Sheet3.ListObjects("Table3").Range.Cells(1, 1).Row
With Sheet3.ListObjects("Table3")
Set rngOLDBDY = .DataBodyRange
.Resize .Range.Cells(1, 1).Resize(iTBL3rws, .DataBodyRange.Columns.Count)
If rngOLDBDY.Rows.Count > .DataBodyRange.Rows.Count Then
For Each rng In rngOLDBDY
If Intersect(rng, .DataBodyRange) Is Nothing Then
rng.Clear
End If
Next rng
End If
End With
End Sub
This routine differs from previous one by eliminating preprogrammed cases. When there is a change registered on active worksheet, then any table in this worksheet which is about to be changed will trigger update_Table procedure.
Im using this code/formula. works well for my needs only thing i would like to know is how do i make a better cell formula so i can use 3+ tables as a reference. currently im just nesting a bunch of iferror statements within the iferror
=IFERROR(INDEX(Table1, ROW([#Date])-ROW(Table3[#Headers]),COLUMN(A:A)),IFERROR( INDEX(Table2, ROW([#Date])-ROW(Table3[#Headers])-ROWS(Table1),COLUMN(A:A)), IFERROR(INDEX(Table4, ROW([#Date])-ROW(Table3[#Headers])-ROWS(Table2)-ROWS(Table1),COLUMN(A:A)),INDEX(Table5, ROW([#Date])-ROW(Table3[#Headers])-ROWS(Table2)-ROWS(Table1)-ROWS(Table4),COLUMN(A:A)))))
Im also using the
I have a monster of a workbook that I'm trying to make more manageable for those that use it after me. I have a ton of code that is ran when buttons are pressed to make it more user friendly to those that know little to nothing of Excel. So here is where I need help.
I have several sheets with similar tables. My first sheet contains a Master List of customer information and pressing a button, copies this information to each other sheet and sorts it to categorize these customers on their respective sheets. This allows me to enter new information only on the first sheet and have it auto-populate the sheets correctly to minimize human error.
To cut down on a lot of the errors, I utilized structured referencing in tables. I didn't originally have it this way, but I've been trying to improve this workbook over time.
Anyway, so I have a column "Charge Type" in each table, and the total column references it as
[#[Charge Type]]
which is great, considering customers will be added and removed pretty regularly and this cuts down on errors.
However, when this formula gets copied to one of the other sheets, it's converted over to
All_List[#[Charge Type]]
which adds the name of the table on sheet1, which is "All_List". Now I want it to refer to the column "Charge Type" specifically in the new table on the new sheet, and I cannot for the life of me figure out how.
This solution uses a variable to hold the ListObject "Field" formula then loops trough all other ListObjects in the same workbook with the same "Field" and applies the formula to that "Field".
ListObjects before
Sub ListObjects_Formula_Copy()
Dim wsh As Worksheet
Dim lob As ListObject
Dim rTrg As Range
Dim sFld As String
Dim sFmlR1C1 As String
Rem Get Formula from Primary ListObject
sFld = "Price" 'Change as required
Set lob = ThisWorkbook.Sheets("Sht(0)").ListObjects(1) 'Change as required
sFmlR1C1 = lob.ListColumns(sFld).DataBodyRange.Cells(1).FormulaR1C1
Rem Apply Formula to Other ListObjects
For Each wsh In ThisWorkbook.Worksheets
If wsh.Name <> "Sht(0)" Then
For Each lob In wsh.ListObjects
Rem Validate Field
Set rTrg = Nothing
On Error Resume Next
Set rTrg = lob.ListColumns(sFld).DataBodyRange
On Error GoTo 0
Rem Applies Formula
If Not (rTrg Is Nothing) Then rTrg.FormulaR1C1 = sFmlR1C1
Next: End If: Next
End Sub
ListObjects after
I am returning a Excel.range of a listObject (Excel table), based upon the visible rows, using this kind of syntax (where pLO is a list object):
Set returnUniqueList = pLO.range.SpecialCells(xlCellTypeVisible).EntireRow
This is happening AFTER I do an advanced filter on a column. I can see that the advanced filter has worked, and is returning the correct number of rows through visual inspection.
The problem is that the above code snippet returns a range with many areas, which might contain overlapping rows in the areas! So if I iterate through all the areas in the returned range, I get duplicates. How can I either only return the visible rows, or filter out the duplicates during the iteration that follows?
EDIT***************************************************
Erik, some more information regarding the overlapping. the returnUniqueList range above will have numerous 'Area' objects contained within it. These could number from 1 to n, where 'n' can exceed the number of visible rows in my original table.
Each of these Areas is also a range (so could also contain areas 1..n!!!). Looking at the rows in these areas, Area(1) could contain identical rows to Area(2)!
END EDIT************************************************
I can't do an advanced filter to a different range, because I need to return the table worth of filtered table.
I hope this makes sense.
Cheers,
LazzMaTazz
Try same without the .EntireRow as in:
'Set returnUniqueList = pLO.range.SpecialCells(xlCellTypeVisible).EntireRow
Set returnUniqueList = pLO.range.SpecialCells(xlCellTypeVisible)
and see what the Areas are, and if there are yet any overlapping rows in this result.
The solution I've come up with to this problem is to create a new worksheet in my workbook, and copy the filtered table into this new worksheet.
This always (in my testing with various tables so far) seems to copy the filtered table from the source worksheet into contiguous rows in the temporary destination worksheet. This then returns a range object with a single 'area', which can be used reliably.
I have to be careful to:
make sure I clean the temporary worksheet up when I'm finished working with the data
clear the temporary worksheet cells after each operation so old data doesn't cause me problems.
Private Function copyToNewWorkSheet() As Excel.range
' call this when the sourcesheet (pWkSht) is already filtered.
Dim myWkBk As New Excel.Workbook
Dim tempWs As New Excel.Worksheet
' if the first time this is called, create the new worksheet
If WorksheetExists("TempWorkSheet") Then
Set tempWs = pMyWkBk.Worksheets("TempWorkSheet")
Else
Set tempWs = pMyWkBk.Worksheets.Add(After:=pMyWkBk.Worksheets(pMyWkBk.Worksheets.Count))
tempWs.Name = "TempWorkSheet"
End If
' clear the temp worksheet contents
tempWs.Cells.Clear
' reselect my source worksheet (which is already filtered)
pWkSht.Select
' it falls over sometimes if this isn't here - any thoughts???
pWkSht.range("A1", pWkSht.Cells(pWkSht.rows.Count, "A").End(xlUp)).Select
' copy the required from the course worksheet, using information from the table (pLO) on the worksheet
pWkSht.range("A1", pWkSht.Cells(pLO.range.Areas(pLO.range.Areas.Count).rows.Count, "A")).Resize(, pLO.range.Columns.Count).Copy tempWs.range("A1")
' return the 'clean' range from the temporary worksheet
Set copyToNewWorkSheet = tempWs.range("A1", tempWs.Cells(tempWs.rows.Count, "A").End(xlUp)).Resize(, pLO.range.Columns.Count)
End Function
I can upload a workbook if anyone would like to see the solution in full. This problem has taken me a few days to solve - so please feel free to ask!

I've intentionally offset them by varying degrees from each worksheet's A1 cell in order to demonstrate a structured table's ability to address either itself or another structured table in a formula as a separate entity regardless of its position on the parent worksheet.

Your new empty third table on the Sheet3 worksheet should resemble the following.
Step 2: Populate the third table
Start by populating the first cell in the third table's DataBodyRange. In this example, that would be Sheet3!C6. Type or paste the following formula in C6 keeping in mind that it is based on the default table names. If you have changed your tables names, adjust accordingly.
=IFERROR(INDEX(Table1, ROW([#[no.]])-ROW(Table3[#Headers]),COLUMN(A:A)), INDEX(Table2, ROW([#[no.]])-ROW(Table3[#Headers])-ROWS(Table1),COLUMN(A:A)))

While you cannot retrieve the worksheet name of the source table directly, the CELL function can retrieve the fully qualified path, filename and worksheet of any cell in a saved workbook¹ as one of its optional info_types.
Put the following formula into Table3's empty cell in the first row of the new column you have just created.
=TRIM(RIGHT(SUBSTITUTE(CELL("filename", IF((ROW([#[no.]])-ROW(Table3[#Headers]))>ROWS(Table1), Table2, Table1)), CHAR(93), REPT(CHAR(32), 999)), 255))

These two routines make extensive use of the Worksheet .CodeName property. A worksheet's CodeName is Sheet1, Sheet2, Sheet3, etc and does not change when a worksheet is renamed. In fact, they are rarely changed by even the more advanced user. They have been used so that you can rename your worksheets without having to modify the code. However, they should be pointing to the correct worksheets now. Modify the code if your tables and worksheets are not the same as given. You can see the individual worksheet codenames in brackets beside their worksheet .Name property in the above image showing the VBE's Project Explorer.
Tap Alt+Q to return to your worksheets. All that is left would be to finish populating Table3 by selecting any cell in Table1 or Table2 and pretending to modify it by tapping F2 then Enter↵. Your results should resemble the following.
If you have followed along all the way to here then you should have a pretty comprehensive collection table that actively combines the data from two source 'child' tables. If you added the VBA as well then maintenance of the third collection table is virtually non-existent.
Renaming the tables
If you choose to rename any or all of the three tables, the worksheet formulas will instantly and automatically reflect the changes. If you have opted to include the Workbook_SheetChange and accompanying helper sub procedure, you will have to go back into the ThisWorkbook code sheet and use Find & Replace to make the appropriate changes.
Sample Workbook
I've made the fully operational example workbook available from my public DropBox.
Table_Collection_w_Sheetname.xlsb
¹ The CELL function can only retrieve the worksheet name of a saved workbook. If a workbook has not been saved then it has no filename and the CELL function will return an empty string when asked for the filename.
You can activate the Office Clipboard (arrow at bottom right of clipboard section on Ribbon Home Tab). Copy both ranges then use the Paste All command as shown below.
You would still need to fill down the sheet name in an extra column first though which can be done by double-clicking the fill handle.
Update
To get the same results with formulas try filling down this for the sheet name:
=IF(ROW()<=COUNTA(Sheet1!A:A),"Sheet1",IF(ROW()<COUNTA(Sheet1:Sheet2!A:A),"Sheet2",""))
and then fill down and across this formula for the values in the tables:
=IF(ROW()<=COUNTA(Sheet1!A:A),Sheet1!A2,IF(ROW()<COUNTA(Sheet1:Sheet2!A:A),INDEX(Sheet2!A:A,ROW()-COUNTA(Sheet1!A:A)+1),""))
lori_m made a really good contribution that I built upon by using Microsoft Excel Tables and structured references.
First make a column in your output table called RowID which contains the row number within the table and then use this to fill the data values.
=IF( INDIRECT("Table3[RowId]")<=ROWS(Table1)
,INDEX(Table1[column1],INDIRECT("Table3[RowId]"))
,INDEX(Table2[Column1],INDIRECT("Table3[RowId]")-ROWS(Table1)))
There is a detailed explanation of how this works on my blog as it was too long to include here.
A slight modification to Jeeped's code.
If you happen to use a similar approach, but with several tables (e.g. more than 10), then it will be rather cumbersome to attempt to manually add every name of every table. This is also a problem if you change names of the tables, since the names are hard-wired in VBA. To avoid additional work, consider this:
So, assume the following:
On each worksheet there is one or several tables, but they have similar structure.
There are only tables on worksheets - no other members of ListObjects collection are being present.
Every time we edit a table on a sheet, this will trigger an update in master table (table 3).
Then the Workbook_SheetChange Sub in the example above could look like the following:
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Dim tbl As ListObject
For Each tbl In ActiveSheet.ListObjects
If Not Intersect(Target, tbl.Range.Offset(1, 0)) Is Nothing Then
On Error GoTo bm_Safe_Exit
Application.EnableEvents = False
Call update_Table
End If
Next tbl
bm_Safe_Exit:
Application.EnableEvents = True
End Sub
Edit. The second routine will then look like:
Private Sub update_Table()
Dim iTBL3rws As Long, rng As Range, rngOLDBDY As Range
Dim tbl As ListObject
Dim sht As Worksheet
iTBL3rws = 0
' consider all tables, excluding master table
For Each sht In ThisWorkbook.Worksheets
For Each tbl In sht.ListObjects
If tbl.Name <> "Table3" Then
iTBL3rws = iTBL3rws + tbl.DataBodyRange.Rows.Count
End If
Next tbl
Next sht
iTBL3rws = iTBL3rws + Sheet3.ListObjects("Table3").DataBodyRange.Cells(1, 1).Row - Sheet3.ListObjects("Table3").Range.Cells(1, 1).Row
With Sheet3.ListObjects("Table3")
Set rngOLDBDY = .DataBodyRange
.Resize .Range.Cells(1, 1).Resize(iTBL3rws, .DataBodyRange.Columns.Count)
If rngOLDBDY.Rows.Count > .DataBodyRange.Rows.Count Then
For Each rng In rngOLDBDY
If Intersect(rng, .DataBodyRange) Is Nothing Then
rng.Clear
End If
Next rng
End If
End With
End Sub
This routine differs from previous one by eliminating preprogrammed cases. When there is a change registered on active worksheet, then any table in this worksheet which is about to be changed will trigger update_Table procedure.
Im using this code/formula. works well for my needs only thing i would like to know is how do i make a better cell formula so i can use 3+ tables as a reference. currently im just nesting a bunch of iferror statements within the iferror
=IFERROR(INDEX(Table1, ROW([#Date])-ROW(Table3[#Headers]),COLUMN(A:A)),IFERROR( INDEX(Table2, ROW([#Date])-ROW(Table3[#Headers])-ROWS(Table1),COLUMN(A:A)), IFERROR(INDEX(Table4, ROW([#Date])-ROW(Table3[#Headers])-ROWS(Table2)-ROWS(Table1),COLUMN(A:A)),INDEX(Table5, ROW([#Date])-ROW(Table3[#Headers])-ROWS(Table2)-ROWS(Table1)-ROWS(Table4),COLUMN(A:A)))))
Im also using the
