For the record, HDTBL works just fine.  I ended up with code like the
following (for A0 paper):

  .po    1c
  .sp   |0.5c
  .TBL cols=12 width='9.7c'
  .ll    116c
  .pl    116c
  .PSPIC file.eps 9.7c
  ....  more .TD, .PSPIC lines
  .PSPIC anotherfile.eps 9.7c
  .nop  \" when no EPS file is needed here

And executed groff as:

  groff  -mhdtbl  -P-l -P-p -PA0 >

to get a nice landscape plots with a maximum of 12 columns (some had no
EPS files).

The only concern was a multitude of error messages: Table width larger than column width.
To avoid this warning You must a) place the .ll request before .TBL and b) increase the linelength a little, because 12x9.7 is 106.4. multiplication overflow division by zero
These messages result from a bug in hdtbl.tmac. (I didn't test with extreme long lines.) I will look for it as soon as possible.
    --- last 2 lines repeated many times --- multiplication overflow division by zero numeric overflow numeric overflow numeric overflow
    --- last line repeated to the end of input ---

where line 24 was the .TBL line above, and lines 29, 31, 33 and all
PSPIC lines thereafter were the 'numeric overflow' lines.

None seemed to do any harm, but clearly there is a problem.

Regards and thanks for the help,
