I used to right click in excel to do this but I don’t see the command on my calc sheet, using 6.3.5.2
thanks
Please try right click on the header of colum (letter row)
Or choose Format - Columns - Hide
Also you can add hotkeys for this operations - choose Tools - Customize - Keyboard tab
Or you can create your own buttons on toolbar
thank you very much, so easy to just right click.
