Thanks again. It's not quite what I'm after as it would be on the same
line as the last in the paragraph (or one after), but another cell might
be higher. So it might not always end up at the absolute bottom.

Anyway, you all provided already so much help. As I'm a Context newbie
I'll just take the to play around with the stuff and see if I can come
up with something that suits my needs. I'll start a new thread in case
I've a more more specific question.

Cheers,
