Yeah there are options for changing border-widths and other things but if they are set in the html it doesn't work with any of the values I tried, and I tried everything that looked to be remotely like it could change those values.
Didn't think of letting the class be and not setting the cellspacing and cellpadding though, then it would probably work with the css.
It works now at least, I'll leave it at that for now. =]
