How to change the separator line width and color for TableLayout?

We are using TableLayout with groups. We are not able to modify column separator line width and color. Thick column border looks odd. So we have a requirement to modify the border width and color.
Any help would be highly appreciated.

That’s a matter of setting Shape.strokeWidth and Shape.stroke.

What is the problem?

We are using this layout

If you see the thick border between two columns. That we want to control.

Have you tried setting the Shape.strokeWidth on the Shape in the Group template?

Thanks for your help Walter. It’s working.
