I can confirm this problem on my system. Can you send along the .ui file
used to create table? I can submit a bug on your behalf once I have that
file.
The problem seems to be a bug in pyside-uic. It creates a brush for the BG,
then replaces it with the FG brush, and then applies that brush to both the
BG and FG. The background is white in the 2-4 cells because the FG brush
style is set to QtCore.Qt.NoBrush, probably because text only uses the
color, not the brush type (i.e. text cannot have a diagonal pattern, or a
gradient). Since this FG brush gets applied to the background, the
background defaults to white. When the text color is not specified (i.e. it
defaults to black), then a FG brush is not created and the background shows.
I expect that if you were to manually specify the text color as black, then
the background color would always be white.
