Thanks for your response. I got lost trying to follow your idea. In the
past I have subclassed my own classes and reimplemented methods in order
to make changes suiting the subclass. But here I cannot even make the
simplest reimplementation of paintCell. For example, the method,

  def paintCell(self,p,row,col,r,selected):
        QTable.paintCell(self,p,row,col,r,selected)

produces an error message (13 times, yet):
  TypeError: paintCell() takes exactly 6 arguments (7 given)

Furthermore, I don't know how to identify the QPainter object that Qt
passes. I could not find any place in the documentation that describes
how to do this. In my attempt above, I created one.

I did try other approaches, but they did not work either. If you could
suggest a reference to code, I would be grateful. Thanks.
