Avoid selection of ColumnHeaders when all rows are selected [message #1075557]

Hi,
I am trying to find a way to avoid having the column headers selected when all rows in the table are selected. Especially when all rows are selected because the table only contains one row that is then selected automatically (because there is no way to get rid of this selection!).
The problem with the column headers being selected is a) it changes colors and b) when resizing one column, all columns are resized.
Could anyone tell me how to do this or at least where to start looking? I couldn't find any command that is triggered to do the automatic selection of the first/only row.
My table has row selection enabled, so I suppose that is why all the headers get selected :-/

Thanks,
Geraldine

Hm, well what you might could try is to create a custom RowSelectionModel and override isColumnPositionSelected() to always return false. Not sure what other impact that might have. Maybe you need to implement it with more logic so no other use cases break.

Thank you, I created a new SelectionLayer that always returns false for "isColumnPositionFullySelected". This solved the layout and the resizing problem. Since we disabled the feature to select an entire column (instead, the table is sorted when clicking on the header), I hope it won't have any negative consequences.

Cheers,
Geraldine
