Also, have you modified the color of the "Normal" paragraph styles?

The "Normal" paragraph style is applied to all table cells. Unfortunately,
if you've modified some property of the Normal style, that will be applied
in the table style too... You can't define that property in the table style
any more.

So, if you use table styles, it's best to leave the Normal paragraph style
untouched from its default.
