In my ongoing search to further improve table layout for my beamer-presentations, I just came across a simple way to change the font color in tables. This comes in handy, for example, to highlight results regression results in specific tables.
Instead of, for example, specifying a 2-column table with two centered colums as
\begin{tabular}{cc}
add >{\color{red}} before the column definition that you would like to have printed in red (or whatever color you specified):
\begin{tabular}{c>{\color{red}}c}
If you would like to add this feature as an overlay, simply add the corresponding number, e.g. 4
\begin{tabular}{c>{\color<4>{red}}c}
So that it will only be shown on the fourth page of this slide
Necessary usepackages: \usepackage{xcolor}
