How about this:

Positioning on table-column and table-column-group items affect their corresponding table-cell items as though those table-cell items were selected in the same rule. Table-cell items spanning more than one column (as with HTML's 'colspan') are only selected by table-column/table-column-group when they originate in a cell starting in the column(s) of the selected table-column/table-column-group.
