I have a problem with the new tables :
When I change the background color in a specific cell with black text, and I pick a color such as dark green, my black text changes automatically to "white" . It is really annoying as I sometimes have my text written in different colors, not only black, and I have to readjust everything.
It is a nice idea in theory to automatically adapt the text to the background color used, but not in practice as it messes up the existing layout. Or at least, put an exception to the rule and don't change the text color when it is different than the default one (black).
