That appears to be exactly what I was after!
(Sorry I don't have MKIV set up right now but will try it when I can).
I don't know if it is of general interest.
I find that writing documents for context - once you get used to it -
is much nicer than using a wordprocessor.
But the process of entering tables remains tedious and error prone,
compared to e.g. the Word equivalent that many will be used to.
