This doesn't work once you start spanning columns. Imagine the  
following html table:

         <td>Cell 1:1</td><td>Cell 1:2</td><td>Cell 1:3</td>
         <td colspan="2">Cell 2:1</td><td>Cell 2:2</td>

Using tr:nth-child(3) to highlight the third column breaks here. It  
also could not handle adding or subtracting columns dynamically. I've  
argued for this before on the list, and have always been told it's an  
implementation nightmare. But it /is/ necessary if we truly want to  
use tables for data.
