* The test is supposed to assert that "[c]ontents of a cell which spans  
through a collapsed column are clipped", but Firefox 3.6.12 passes the  
test even though it doesn't clip anything (as can be seen by removing the  
black background).

* Spec seems entirely too unclear, it just says cells "are clipped" and  
doesn't clarify how. Opera clips the part of the cell that would have  
shown up in the second column had it not been collapsed. (This makes the  
most sense to me (though Opera doesn't do it correctly for RTL and  
collapsing the middle of bigger colspans), but makes the TC show "FAIL  
FAIL".) IE8 seems to always clip from the right-most side (left-most in  
RTL tables), regardless of whether the clipped parts would fall in the  
collapsed column or not.
