xCode 11 on Catalina -  I set the background color of rows in my table view - the color goes right to the edge of the table view.

xCode 12.3 beta on Big Sur - I set the background color of rows in my table view - the system leaves a white margin down each side of the table view - about 3mm or so wide.

This is older code, hence using cells in the table not views.

I want the color in my table view rows to go right to the edge of the table.
