In nroff they're drawn using \l and \L.

Does this mean that tbl can't make horizontal rulers
in its tables in nroff mode, or is the drawing of
them implemented bypassing \

Hello, Werner.
Many thanks for the info. I see that the problem
lies deeper than I had thought.

It's a problem which I don't know to solve while keeping tbl device
independent.
In troff PS mode, the registers \n[.H] and \n[.V] (the resolution in
horizontal and vertical units,
Hello all,
I have found what may be a bug either in tbl or in
groff's \D request. Or I don't understand how either
works. The same piece of code typesets differently
in troff and nroff modes:
.ll 36n

The line below should be the current line-length:

\D'l \n[.l]u 0'
