Groff hdtbl tables disappear near the footer

[Mike]

Hello,

I am new to groff. I am more a designer than a coder, so my
understanding here may be lacking.

I created a CV template using groff + ms macros + tbl + hdtbl. To be
fair, it worked wonderfully. I was able to replicate what I had
previously done with LaTeX. Including adding hdtbl table entries with
macros.

There is just one issue. I cannot get my head around why the tables
created by hdtbl vanish as they approach the footer.

If I place 6 tables in a row, tables one two and three will show on the
first page, then tables 4,5 and 6 are gone. the following content is
seen on the next page but not the tables (they appear to have been
swallowed).

I noticed, however, that a page break after the 3rd table causes the
next 3 to appear on the following page. One caveat, sometimes when
content moves, one of the middle tables (3 or 4) vanishes again, while
the last few flow onto the next page.

Perhaps this is by design and I am just naive to it, but I would love
to know the cause and what I could do for reliable results.

Kind regards,

Mike
