Natural tables have “odd” and “even” keywords for \setupTABLE but none in the way you like it. What I would do is to use a overlay in combination with metapost to create the background but there is no global register to access the current column/row of a cell, e.g. \currenttablecolumn (this name is already used by tables) and \currenttablerow.
... Maybe \currentTABLEcolumn (no collision with tables' \currenttablecolumn) and \currentTABLErow could be defined for this purpose.
I agree. In addition, \currentTABLEheaderrow, \currentTABLEheadercolumn, \currentTABLEfooterrow, \currentTABLEfootercolumn, and the \max... version of all of these are also useful at the user level. Aditya
