I have the following stylesheet setup and the column width of <TD> works well in Firefox but not IE. The left hand panel is narrower than the right hand ones and I do not have excessive long text or whatsoever at the right hand panel. Any idea?
What about cellpadding/cellspacing in your HTML section or margins and padding in your CSS? If you have any of those, then your widths won't quite work. Other than that, have you considered playing with your widths to figure out if IE's simply making a miscalculation?
