It has nothing to do with tbl.  It's a feature of ms, which
resets font size, vertical spacing, etc. to the values given
by those number registers, at every paragraph.  TS calls LP,
which (in groff's version of ms) eventually calls address@hidden,
as far as I can tell.

You may want to look at the original ms manual by M. E. Lesk,
groff's documentation (info groff), and perhaps read the code
of groff's s.tmac.
