I'm having a bit of trouble with Sheet.autoSizeColumn.
Using the same data
if I use Excel's built in Format/Column/AutoFit Selection feature, I get a column width of 1.07"
if I use Poi on my dev box, I get a column width of 1.25"
if I use Poi in my target environment, I get a column width of 0.96"
What do I have to control to get consistent sizing in different environments?
You can also set the column with "hardcoded" like this:
sheet.setColumnWidth(short column, short width);

I recently wanted to create an excel table to note all my electric components that I have so I can easily find the right component without searching every time for it.
The problem is, especially with capacitors, they come with a wide range of values generally for me between 220uF and 10pF, and I want to create a custom format to display the values properly in excel, for example if I put in a cell 0.00022 it shows 220uF or maybe 0.22mF (but 220uF is better) and not 2.2E-04 or any other format.
I tried the custom tool but I don't know how to add the micros, nanos and picos.
You can add conditions to the formatting, like:
[<0.00001] 0.00%%% "pF";[<0.001] 0.00% "uF";#
This will show 2.20%% uF in the cell (so you can multiply by using the percent sign, more details here).
Drawback: the percent signs are shown, and the Ctrl+J trick described on the link does not really work for me (and I personally find it as an ugly solution).
If I were you I'd add a new column called "Formatted" where I multiply the values with formulas. Like
=IF(A1<0.00001,A1*1000000 & "pF",IF(A1<0.001,A1*10000 & "uF"))
It's easier then to search in both columns (one is by formatted, like all "uF", other is by real Farad value. Also you could use the original column for sorting.
I want to create an Excel Table where the first column is the "SL" (serial number) column that starts from 1 and then increases by 1 for each subsequent entry. I want the serial number to automatically increase as I add more rows to the table.
I have tried using all manners of "=ROWS" functions, all manners of "=COUNTA" functions, and all other functions used in tutorial that I found in the web. None of them are immune from sorting or filtering. That is, if I sort the "Name" column from A to Z, the serial number that was assigned to its respective row entry changes because of how these formulae are written. For example:
This is the Original List. As you can see, Dragon Fruit's serial number is 1. I have used the "=COUNTA(B$2:[#[NAME]])" function in this example.
As you can see, when I sorted the "Name" column from A to Z, Dragon Fruit's serial number went from 1 to 2, Acai went from 4 to 1, Guava went from 9 to 3, and so on. But I want the serial numbers to be static and locked to their corresponding "Name".
Is this possible to do in Excel without manually typing the numbers in the SL column?
Good question and a tricky situation to deal with. I'm not sure if the question is better suited for SuperUser though.
The trick here is to somehow use absolute cell-references instead of relative ones. As you have now experienced, Excel filters won't work well with relative references. However, manually adding absolute references is not what we want to do.
To mimic the absolute cell-reference behaviour you can preceed the row reference with a sheet-reference which magically should counter the normal formula-behaviour and turn them into actual absolute cell-references:
Formula in A2 (which will auto-fill the 'SL' column):
=ROW(Sheet1!A1)
Data when filtered A-Z on 'Name':
Data when tabbed a new row:
You could use PowerQuery in Excel to add an index in front.
Remove the ID from your source.
Make your source a table
Import into PowerQuery and add an index
Load the output to another sheet. In this sheet you can filter and sort and everything you want.
I have an Excel sheet with a very wide table on it. Due to developer friendlyness I'd like to use a certain style of column header naming (much like proper Hungarian notation), where I suffix each header name with "column type" tags. This allows me to easily spot where e.g. apples and oranges are compared. There are also pivot table reports based on this table.
An example to illustrate this: say you have 2 monetary columns, column A being expressed in another currency than column B. The model should thus never combine them without first applying appropriate exchange rates. To spot this I name these columns e.g. Earned - Cur1 and Saved - Cur2. Any calculation like =[#[Earned - Cur1]] + [#[Saved - Cur2]] is illegal, but due to the tags this can be picked up easily in an audit. I have several such tag groups in use already, and they already prevented some errors creeping in.
However...
The file also needs to be distributed to lots of not-so-savvy end users, and they need to fill in this table and refer to some of the outcome columns. Most intermediate columns we already hide, but the column names are now far from being user-friendly (like: fill out Actual - NK/Q1/EC/%, please?).
And this needs to run in Excel 2010.
What are my options?
Option 1
Add an extra row above the table, putting human readable names in there, and just hide the table header row. This works, but not the users can't sort and filter the table anymore, so that's a no-go.
Option 2
Augment option 1 by prepending a newline to each column name, and make the table header row 1 character high. The header cells would still be there to drive sorting and filtering and the users have human readable names in the row above. The actual header cells would appear like 'empty' buttons. Could work, but then the complex formulas become unreadable due to all the newlines from the column names all over the place.
Option 3
Add a macro that switches the headers in the table by alternative headers in another row above the table. The macro should be ran just before sending out the file to the users, and ran again when they return them filled in and all. I happily coded this option into the file, and it works wonderfully! But then I realized this (and thus option 2 as well) breaks all the derived pivot tables, since Excel links the data by the names used in the table - update the name, and that section of the pivot will be dropped...
I'd really like the option of having our development-oriented column names in there when we ourselves work with the file, but being able to switch out the headers when needed. And of course without rebuilding all the pivots after each such switch.
An opening here would be that pivots seem to only drop the columns once they're refreshed. I could use this to update the header names, then do some magic on the pivots to remap their fields, and only then refresh them, but it seems there's no way from within VBA to accomplish that (PivotField.SourceName is read only).
Hopefully someone can think of an alternative, or am I SOL? I'm totally open to other workarounds.
Workaround 1
Insert null-terminating characters in the header names such that they do not show normally in the formulas, but do not show in the table header row. If only it were that simple though... Turns out Excel throws up from a =Char(0)&"abc", and things like =Char(8)&"abc" (tab anyone?) give Unicode replacement characters when pasted into a header cell... (?)
Workaround 2
A last resort seems to be to unzip the excel file, and plough through the xml data to update everything in one go there, then rezip the file. But this code also needs to be executed by less skilled users, and I see too many ifs and buts to make me feel safe using this setup.
Workaround 3
For now I just use a variation on option 2; I have some VBA that 'empties' the header cells instead of prepending a newline to them. By 'emptying' I mean setting the font size to 1, subscript, non-bold, and then make the font color identical to the background color, followed by setting it's row height to the default 14.5. The cryptic names do leak out however; column header cell drop down arrows for sorting&filtering show the cryptic name, as well as the pivot field settings and of course the formula bar when you just click such a cell. But I guess it's the best I can do?
And then again I'm probably just perfectionizing this thing faaar to much :) But from this point on it's about the challenge!
Make sure you Tick the Box "Add this data to the DataModel" when creating your pivot(s)
AFAIK when your Pivots are connected to the Datamodel instead of directly to the Range/Table you can change your column-names in the Table and your Pivot will stay fine. You could even use other names in your Pivot.
I can only figure out how to color 1 column - I'm trying to color the whole row based on the Wellname.
You can color alternate rows by adding a rule in Properties --> colors
1. Click Add Rule
2. select Rule Type = Boolean Expression
2. Value = Mod(RowId(),2)=0
unfortunately Spotfire doesn't support row-based coloring.
if you're creating an analysis with multiple visualizations, you could potentially use a details visualization to limit the rows displayed in the table to a selected well.
This is an answer I found on Tibco Community:
You can put your expression instead of the one from an example.
I'm using excel 2007.
I've a list of tasks (200-500) that I need to group in different category/section etc (multiple filters). Whole data is in excel table so I can apply Excel's build-in table filters to display exact data that I need.
However it is always difficult to apply multiple filter to display expected data, specially as I need to do it very frequently. To make things simple I'm planning to number each record like
a.b.c.d.e.f
Where a, b, c, d, e, f are simple numbers. List looks like:
1
1.1
1.2
1.2.1
1.2.1.1
1.2.2
1.3
& so on.
Problem is, Excel take it as number with single decimal but as soon as I add second decimal, excel treat it as text, which is obvious in general behavior.
However, as special case, I need excel treat both as number or text. Number is preferable as I want to sort them, which might be difficult as a text.
To make the things little more complex, while filtering in table, I require if I can add some formula to filter results like 1.* should display all numbers starts with 1.
Is it possible with excel's default behavior, without VBA?
If no, is it possible with VBA? If yes, any clue is appreciated. I don't need whole program as I can write basic VBA program, just a clue how it can be done?
I sort mine by adding a helper column that adds a letter to the front and sort on that. E.g. 1 becomes f1, 1.1 becomes f1.1 etc. Then all are sorted as text.
You can use the formula ="f" & A1.
My sample:
Then the data sorted:
And the filter:
If I were to try this without VBA, my first step would be to use the sort to columns function on the data tab.
Next make sure all empty spaces in your data are filled with zeros.
Then sort the data by column
as long as you left your original data in the same row as the sorted data (I didn't in the images posted to focus on the process), your items should now be in order.
