How can I resize log columns on Windows 10 touch screen (tablet)?

Any hint about how the columns in log viewer (or probably pretty much column width anywhere) can be resized when you’re on a (Windows 10) tablet? It seems an almost impossible task (probably requiring either microscopic precision or some trick I have yet to learn).
It’s a straightforward task using a mouse or a touchpad - you just wait for the horizontal arrows to appear, and then move left/right - but with a touch screen, I’m only successful in 10% of tries; all the rest usually result in activating the sort by either of the columns on both sides of the delimiter I’m trying to move.
