I hope that the CSS WG accepts Anne's objection and defines rendering  
in a browser-compatible way.

For the table integrity checker I implemented what browsers do: A  
cell slides to the right until there's a free slot for its top left  
corner. If the cell spans multiple columns and overlaps with a cell  
still in effect from an earlier row, it is an error, but doesn't  
cause the cell to move further to the right. Since browsers  
interoperate, I think it would be a bad idea to change this behavior.
