TableWidget.item(row,column).setBackground(color) has no effect when using apply_stylesheet

I'm a newbie to Pyside6 and qt_material.

I used the source code at the end of this comment.
But self.item(row, column).setBackground(color) has no effect when I use qt_material module.

Can I resolve this issue?

#55 (comment) (add custom-stylesheets) did not work in my case.

• Without qt_material

without-qt_material.mp4

• With qt_material

Do you have an opinion on this?
Since you seem to have answered questions #55 and #65, I assumed you may have a solution to this issue.
