For headers, you can use: table.wikitable tr th { color: white; } That will target header cells of all tables using "wikitable" as a class.

That other table uses the class "navbox", so you can look for any rules for "table.navbox" in your custom CSS and change or add them as appropriate. Since it mostly contains links, keep in mind that it uses the usual color scheme for links depending on whether the target article exists. If you want to bypass that, you would need something like this (not tested): table.navbox tr td a { color: black; }
