[reportlab-users] Format cells inside table

[Jakob Damgaard Møller]

Hello Chris,
i should just "figure" how the Tabletyle was working.
I wanted to set the color when i added the "data".
But now i just create the data and the tableStyle in the same loop. So i
got what i wanted. :o)

Thanks for your help
