Many table templates, such as STDT, result in tables that are not easily readable on the DarkVector skin. You often have to highlight the table to be able to read it at all. For the most part, this is because things like background color are explicitly set while text color is not.
Since the DarkVector skin is installed on the site, a mod should be able to edit the css to create overrides for tables and/or templates. As a bandaid fix, I believe simply inverting the background color should be enough to make them contrast with the default skin text colors. The trick should be how to only invert table's background colors when they've been explicitly specified?
