In case you had invoked groff instead of the pipe `tbl ... | troff
...', you would get these error messages:

  test.tr:15: warning: numeric expression expected (got a special
                       character)
  test.tr:16: warning: number register `3tbw4,14' not defined
  test.tr:16: warning: missing closing delimiter

This already gives you a hint where the problem is: The last field is
defined to be `n', but the data is -\D'...', which is incorrectly
parsed by tbl.

But I think this is what Russell wants to have!  Here an example how
to change the thickness of horizontal lines.  The `.nop' operator has
been added in version 1.17 -- tbl only handles troff commands if they
start with a dot.  It's best to control the thickest lines with
`linesize', adding proper \D'...' commands surrounded by \Z'...' to
make lines thinner (the \Z compensates the motion caused by \D).
Otherwise, lines will stick out to the right.
