Selector for the column currently being dragged?

DinoMC

Hi,

I have a table with ColReorder and I'd like to highlight the column that is currently being moved by the user to make it easier to see.
But I tried pausing the page while dragging and looking at the code and I can't see any class or anything being added to the corresponding cells/header.

Is there any way to do this I'm missing?

Thanks!
