I am not saying that the second pass should be done after the document  
loads, that would not useful at all, I agree with you on that indeed.

The key sentence is "The  second pass would be done right after each  
element is laid out." Those elements being table-cells, in this example.

The pass concerning whether that table cell belongs to a certain coloumn  
would be done immediately after that specific cell is laid out, not after  
the document is loaded, and table cells should use the size defines  
padding + border + content-size method so any change in border and padding  
parameters would not require a reflow. Of course, changes in color does  
not require a reflow either. Even with a reflow that may be caused by a  
font-size change, the change is made per cell, so only the last row is  
affected for the reflow, which is very easy on the UA's.
