Happy Monday Everyone!
Have a question and hope you can help. I have a budget spreadsheet that has a budget tab. On this tab is about 8 tables broken down into different categories. Every table in the tab has the exact same columns. Is there a non-vbscript/marco way to create a master table that combines all of the tables into a single table in a different tab. This seems like it would be a no brainer but I have tried everything I can think of and find online and there doesn't seem to be a decent solution without an addon called power query.
I know you asked for a non VBA way, but for completeness I'm adding another answer that also has a VBA solution, because it's dead simple, it's blazingly fast, and it's generic. All you need to do is cut and paste this code into a standard code module, add a button and assign it to trigger the calling routine, give your source tables a name includes the full name of the summary table, and you're good to go.
Sub CombineTables(loDest As ListObject, Optional lcSource As ListColumn)
Dim ws As Worksheet
Dim lo As ListObject
Dim lc As ListColumn
Dim rDest As Range
Dim lDestRows As Long
Dim lSourceRows As Long
Application.ScreenUpdating = False
If lcSource Is Nothing Then Set lcSource = loDest.ListColumns(1)
If loDest.ListRows.Count > 0 Then loDest.DataBodyRange.Delete
For Each ws In ActiveWorkbook.Worksheets
For Each lo In ws.ListObjects
If lo <> loDest Then
With lo
If InStr(.Name, loDest.Name & "_") > 0 Then
On Error Resume Next
lDestRows = loDest.ListRows.Count
On Error GoTo 0
lSourceRows = .ListRows.Count
If lSourceRows > 0 Then
'Work out where we want to paste the data to
Set rDest = loDest.HeaderRowRange.Offset(1 + lDestRows).Resize(lSourceRows)
'Resize the destination table
loDest.Resize loDest.Range.Resize(1 + lSourceRows + lDestRows)
For Each lc In .ListColumns
Intersect(loDest.ListColumns(lc.Name).Range.EntireColumn, rDest).Value2 = lc.DataBodyRange.Value
Next lc
Set lc = Nothing
On Error Resume Next
Set lc = .ListColumns(lcSource.Name)
On Error GoTo 0
If lc Is Nothing Then Intersect(lcSource.Range, rDest.EntireRow).Value2 = ws.Name
End If
End If
End With
End If
Next lo
Next ws
Application.ScreenUpdating = True
End Sub
And here's the caller:
Sub CombineTables_Caller()
CombineTables [SomeName].ListObject, [SomeName].ListObject.ListColumns("Source")
End Sub
When I push that button, the code will look throughout the workbook for any tables who's names contain the name of the Destination table (in this case the Table called "SomeName"), and then bring their data through. So if you are adding new tabes, then as long as you prefix their Table names with the name of the destination table, they will be included. Any other tables (such as the one called 'DifferentName' will be ignored.
...and here's the result:
You can use the functionality of the pivottable wizard to consolidate multiple ranges (which are your tables) together into one pivottable.
When it prompts for you to add your ranges use the table names with the following syntax: Table4[#All]
You need the [#All] to get all the data associated with the table. Just repeat this for each of your tables names you want to consolidate.
Full description i have given in my answer here:
combining data from two sheets and generating pivot table in another sheet
Note: If you want to keep the original table names or table numbers you will need to select the option:
1) "I will create the Page Fields"
2) Enter the Ranges using the table name e.g. Table4[#All]
3) Select how many page fields do you want 1-4 and add item label used to identify the selected ranges below e.g. Table4.
I am not sure if 4 items is the maximum or if this can be extended through VBA. However you can also use PowerQuery or UnionQuery.
The following quotes are from here: http://www.contextures.com/xlPivot08.html
I include some outline in case links are lost.
PowerQuery:
If you have a version of Excel that supports Microsoft's Power Query add-in, you can use it to combine the data in two or more tables. The tables can be in the same workbook, or in different files.
http://www.contextures.com/xlPivot08.html#videopowerquery
Union Query:
If you can't combine your data on a single worksheet, another solution is to create named ranges in an Excel file, and use Microsoft Query (MS Query) to combine the data.
http://www.contextures.com/xlPivot08.html#union01
If you have Excel 2013 or later, then this is the perfect excuse to go play with PowerQuery, which is now called 'Get & Transform' in the ribbon. You can see something very similar to your requirement in my answer at excel indirect function to read dates and return dynamic values
I strongly suggest you go and look at that thread...even if for some reason you can't use PowerQuery for this particular challenge, because I reckon it's worth seeing just how simple it is to mash together identical tables using PowerQuery, even if just for future reference. It's basically a VBA developer in a box. It's a VBA gimp!

I have an excel sheet with a table and its quite large so I also have a slicer to break it up in viewable pieces. My problem is that then selecting a specific unit in the slicer sometimes there will be columns in the table that's empty. I would very much like to make a button to hide them (and then have another button to unhide so I can select other units in the slicer and view new data and so on...)
My problem is that most VBA code online hides all the columns outside the table. Im not in any way fluent in VBA. I have unsuccessfully tried to modifying code I found only. From what I can see online, most codes define an area/range within a worksheet and then loops over that range and hides all empty columns. But then I try to redefine the range as the ListObjects("Table1")the code fails.
So far i have managed to make code that unhides all columns outside the table and I have tried to make a small piece of code that hides the
Sub ShowHidden()
Rows.Hidden = False
Columns.Hidden = False
End Sub
Sub HideEmptyColumns()
ActiveSheet.ListObjects("Table1").Columns.Hidden = True
End Sub
The latter fails
Is it possible to make code that hides empty columns in a table in excel and if so, how does the code look
Kind regards
Need to use the properties of the ListObject object (Excel), in this case use the DataBodyRange to set the range to loop after.
You'll also need to use Range.SpecialCells method (Excel)
Dim lo As ListObject
Set lo = ThisWorkbook.Worksheets("DATA").ListObjects("lo.Data") 'change as required
For Each rCol In lo.DataBodyRange.Columns
'… Here goes the validation of the cells within the column (i.e. rCol)
If … Then rCol.EntireColumn.Hidden = True
Next
To unhide the columns use:
Dim lo As ListObject
Set lo = ThisWorkbook.Worksheets("DATA").ListObjects("lo.Data") 'change as required
lo.DataBodyRange.EntireColumn.Hidden = False
following setting
1 worksheet with raw-data
1 worksheet per week (e.g. week 31, 32, ...)
the raw data gets copied with an user action the current worksheet. however since the table name already exists in another week, table name "tableweek" the next copy of the worksheet gets its table renamed "tableweek2", "tableweek3" etc. since this is unpredictable I'd prefer to name the table same as a variable of the worksheet so I can use the table name in further macros and pivot.
however with all the topics about dynamically renaming table names I couldn't figure out how to correctly set it and hand it over to other macros (in other modules)
the best I've found is
Sub RenameTable()
With ActiveSheet
.ListObjects(1).Name = "MyTableName"
End With
End Sub
however that is just manual when i combine it with a dynamic name (e.g. formula from a cell) I don't get it to work. furthermore how to hand it over to all other macros.
thanks for any help or pointing directions.
Seems I wasn't that far from the solution:
Sub RenameTable()
Dim tblName As String
tblName = Range("D8").Text
With ActiveSheet
.ListObjects(1).Name = tblName
End With
End Sub
Now I just need to hand over that "tblName" and that should be it.
Sharing it in case someone else likes that "solution"

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

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".

.Resize .Range.Cells(1, 1).Resize(iTBL3rws, .DataBodyRange.Columns.Count)

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
