Header Issue

[YvanZim]

For some reason, I'm unable to copy/edit a title cell (the first row). Clicking on it selects the column.
It would be nice to be able to diable the headers in some situation

This is the standard behavior (with MS Excel as the reference).

If you want to copy the header, simply scroll back to the top — you'll find the headers in row 1, where you can copy or edit them as needed. 😊

The FixTop button toggles the first row to be shown in place of the column numbers, but this is for viewing purposes only.
