Thanks! This works. Next time I should read the fine manual to spot the GNU extension. tbl(1) says d,D Start an item vertically spanning rows at the bottom of its range rather than vertically centering it (GNU tbl only). The use of \^ in all the rows' columns is novel to me. By `vertically spanning' the man page strictly means \^ and nothing but it seems; a cell that uses T{...T} and requires more than one line isn't affected. Also, I note the \^:\^ row takes no space; the resulting PDF is identical to my \n[3bot] bodge. Thanks again. Cheers, Ralph.
