Ah. I assumed that there was a lookahead on each element before it was
rendered (that's how I would do it), which would look at the source as
a stream of blocks, and not a stream of lines. Now I understand why
centered tables look the way they do. OTOH should centered text not
be block centered.

Hm. Since each child would have its own structure of lines and environment,
I fail to see the messy part. It seems logical and straight forward to
me. Every block would have a dataarea holding the needed information
about it, height, width etc., which is used by the parent to insert it.
All you need (as someone mentioned in the old table thread, Al Gilman
I think) is a subscreen renderer. (But then I don't know squat of how the
rendering mechanic of Lynx works.)

I've just finished my table parser in perl and it works fine, albeit
a little slow, what I need is a way to let my tables follow the current
environment. Now I see I must do it myself (not much trouble, though).

Anyway, thank you for your answer!

Luck, Gunnar!
