Is there a way to make certain listbox column dividers bolder or thicker than others? For example, make every fourth column divider bold.
The vertical and horizontal grid line offers only visibility and color options. Also, they are global to the listbox object, not independent per column or row. So, there is no built-in option for you to do what you are asking.
But that would be useful…
To be more specific : we don’t need much. In my opinion, Normal, Bold and None would be a very good start.
Would having useless, 1 pixel, columns be a problem?
Actually, that looks pretty good. I might try that.
