Yes, I agree, although the real TableLM gets quite slim this way. But
I'll better just get on a bit and see where it leads. FYI, I've already
got rudimentary element list combination (i.e. without row-spanning).
I've been able to reuse most of my column/grid setup code. I expect the
same will be possible for border resolution. I'm currently determining
how best to do the addAreas stage with the infos I get from the Position
objects. The stuff is all carved into little pieces and I now have to
put it together again.

Good to hear. Thanks for the feedback!
