Resizing column width on touch screens

[commodore]

How can one resize column width on a touch screen (without using a mouse, that is)? I tried aiming my finger or my stylus at the middle line, but without success - it either sorts by one of the columns or opens a menu.
With the pane divider, on the other hand, I had no issues resizing the panes.

Try using configuration dialog: Tabstops page for full column view or Custom Columns page for a custom column set.
