Because "tableau->petit tableau" is not a table.

This is more clear in the english version, where
you have "table" (which is in fact the table in
the sense of "table inside a book", thus, it's
not a table), while the real "tables" are in
fact the "tabular" and the "block" (insert->
table->plain tabular/plain block).

Granted, this part of the UI is not clear...

It's because "20" means nothing, if you write only this,
there is no unit !

For example, "20mm", "20cm", "1.5par" would be meaningful
lengths. I know for sure that there is a page somewhere
in the TeXmacs documentation about units, but of course,
it's not (obviously) understandeable how to get it from
the Help menu... yes, in fact it's at the end of the
page:
Help->Reference guide->The TeXmacs format (see section 8,
"TeXmacs lengths").

Yes: as I explained, it works in a more precise way,
by means of a unit system, while HTML images have
less units (without anything, it's pixels I guess,
and with "%", it corresponds to "par" and "pag" in
the TeXmacs unit system).

This being said, I'm not sure the TeXmacs->HTML converter
understands how to do it...

But it's quite feasible to understand the related Scheme
code, to correct it if necessary, and then send a patch
to us.

P.S.: Please post to TeXmacs users, otherwise I'm the only
