So today I finally found a part of the HTML 4.01 standard that Internet Explorer 6 (and 7) follows better then FireFox 3 and Webkit: <colgroup> and lt;col> tags. Apparently, neither FF3 or Webkit (and thus Chrome) bother to implement these tags. Normally, FF3 and Webkit are on the right side of standards, so its kind of a disappointment, especially when I need the functionality of those tags for a project.
If you aren't familiar with them, browse on over to W3School's XHTML reference and get acquainted. Basically, with column groups you can implement nice things like setting a column's background color without adding classes to each lt;td> in that column.
I hope that FF3 and Webkit see there way to implementing this feature.
