I have 20 columns in my column chooser that can be displayed and all 20 can be non displayed. This will give the user the option to select all 20 and push them to available section and they will not display on the viewer.
There is no way to retrieve the column choosing capability once all 20 columns are hidden. So need a way to disable to done button in the Column Chooser when all the columns are pushed to available side

In the current implementation this is not possible. You could implement your own dialog and register some listener that disables the button in case the tree with the selected columns is empty.

As it seems nobody uses the grid but only column header + body compositions and it seems to be a typical use case for all the users in the world to hide all columns of a table, I will look for a general solution to that issue.

For your information, the "hide all columns" issue is tracked by the following tickets:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=451486
https://bugs.eclipse.org/bugs/show_bug.cgi?id=451490

There are contributions for those tickets that will add the ability to check if hiding all columns is possible. The dialog OK button will be disabled if trying to hide all columns. Also the header menu items will use the check to avoid hiding all columns via menu.

After I was able to verify the contribution and hopefully merged it into core, this topic should be done.
