toggle() does not work on col or colgroup

Toggling a column does not work on a colgroup.

Clicking "Hide Cells" should make the red cells disappear, but instead hides just the cells and applies the col and colgroup to the remaining cell.

This is not a jQuery issue. I think the browser is getting confused by the placement of "this_class" on the cols, which is unnecessary.

Even after your change, removing this_class from the col elements, the colgroup is still displaying. The third column should not be a red color after hiding the first two columns.

I did find a way to make the colgroup hide and that was to set the visibility to collapse and display none.

Since .toggle() is about toggling the visibility of target elements and col/colgroup elements are never visible, I'm not even sure it's a valid use case. Using a class name is probably better.

Browsers probably differ on whether to apply the rules of a colgroup to their respective columns when display is none. The 3rd column is not red in Chrome in my fiddle. Regardless of whether my assumption was correct, this is really not something jQuery can tackle.
