Having thought about this idea a little more, it seems completely 
unnecessary.  Correct me if I'm wrong, but I believe this should have 
the same effect:

table>:not(col):not(colgroup):first-child::before {
   display: table-column;
   background-color: green;
}
table>:not(col):not(colgroup):first-child::before(2) {
   display: table-column;
   background-color: blue;
}

Although ::before doesn't seem to work on elemenents styled with 
'display: table-*' in Firefox or Opera, I couldn't find anything in the 
specs that says ::before doesn't apply to such elements.
