Actually the extra-css-section in skinconfig offers a whole range of options tweaking or enhancing the css coming with your skin.
Since the content of this section is appended to the css provided by the skin, you can override existing css-handles or add your own. So all you'd really need to do is define new classes or ids for your css-table-elements, make sure that the class names don't collide with existing skin class-names and add css-handles for your new classes to extra-css-section. That way you can be sure not to interfere with Forrest css. Note: If you experience any problems along that route, check the Forrest transformations for their preservation of class or id-attributes. There might still be some elements where class or id is not passed to the final output, a bug that is usually fixed rather quickly though. hth Ferdinand
