I think that you summarized the two relevant options correctly.

Does it mean that it is just not possible to freeze first column of Flexitable?

Everything is possible, however if this feature is not implemented then you will need to implement it yourself.

Maybe make 2 identical tables and slide one over the other...

Is this, what you are looking for?



It's a work in progress with the Flexible Table.
Needs still some more tests.

Yes Sir..that is exactly the one

The Flexible Table has been updated in the first post.

Excellent. Works well. To see the horizontal scrolling in action and accentuate the fixed column, I added one more column to the table. I changed this line:
to this line in klaus's code example:

Hello Klaus..Thank you for your efforts
I tested the new Table class in my project. On initial use, the first column freeze worked perfectly, but on adding or removing rows, I got an out of bound exception of array equal to number of columns, pointing to line 681 of the new Table class.
On removing this line, firstcolumn freeze WORKS WELL with all 4 tables in my project now, even after adding/deleting rows..Thank You

I am about to amend some other bugs.
Will have a look at this one.
Thank you for testing and reporting.

Can you please test the attached project.
I couldn't reproduce your error, but I tested with an already somewhat modified project.

Hello Klaus...I tested the class you sent..Now I am getting the following error on initial loading itself, pointing to line 689 of the class. I have 9 columns in my tables.




On fremoving the line 689, which is as follows,all well again

Error log as follows:

Error occurred on line: 689 (Table)

Can you please post your project, or better a small one showing the problem.
From the error message it seems that the number of columns seems to be wrong.
It might depend on how you fill the table.

Hi Klaus..As I mentioned, it is working fine after deleting row no 689 in Table Class.. there seems to be an issue with that..

As already mentioned, I cannot reproduce your error. It works OK in the demo program.
As already mentioned, can you please post your project, or better a small one showing the problem, so I can test and see what happens in your case!

thank you Klaus

So what?
Is the problem solved or not, I don't understand.

Yes solved
