The problem exists independent of the existence of the attributes "colspan" and "rowspan". The problem is that a cell *is not a cell yet* when doing selector matching. Short of doing selector matching twice (once for one set of properties, and then again for another set, with a required layout pass in between the two steps) you simply cannot have selectors that depend on properties. And as I explained a few days ago, doing the two-pass selector matching simply isn't an option, as it would be a performance nightmare. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
