The foregoing advice could probably use some fine-tuning. Is it okay to
use *roff diversions if you let a macro package that ships with groff do
it for you?
You seem to be bumping into an anticipated issue, though.
groff 1.23.0's tbl(1) man page includes the following cautionary note:
Limitations
Multi‐page tables, if boxed and/or if you want their column
headings repeated after page breaks, require support at the time
the document is formatted. A convention for such support has
arisen in macro packages such as ms, mm, and me. To use it, follow
the .TS token with a space and then “H”; this will be interpreted
by the formatter as a TS macro call with an H argument. Then,
within the table data, call the TH macro; this informs the macro
package where the headings end. If your table has no such heading
rows, or you do not desire their repetition, call TH immediately
after the table format specification. If a multi‐page table is
boxed or has repeating column headings, do not enclose it with
keep/release macros, or divert it in any other way. Further, the
bp request will not cause a page break in a “TS H” table. Define a
macro to wrap bp: invoke it normally if there is no current
diversion. Otherwise, pass the macro call to the enclosing
diversion using the transparent line escape sequence \!; this will
“bubble up” the page break to the output device. See section
“Examples” below for a demonstration.
I got good results with the attached document. Here are the commands I
used.
$ nroff -t -mm EXPERIMENTS/table.mm
$ groff -t -mm EXPERIMENTS/table.mm > table.ps
Does this help?
