I can't comment on your problems with the Imagen, but we did run into a
couple of problems with boxed tables vs. TranScript.  I've enclosed three
bug reports (and fixes) that we sent to Adobe.  Since making these changes
we haven't seen any problems with tables on the LaserWriter.  Your mileage
may vary, of course.

XSubject: pscat occasionally screws up tbl output
XIndex:	src/pscat.c 4.2BSD
X
XDescription:
X	Using tbl to generate boxed tables occasionally provokes
X	pscat into placing the bottom line in interesting places.
XRepeat-By:
X	Do enough boxed tables and you will see that the bottom
X	line doesn't always meet left side.  Sometimes, the bottom
X	line will *start* at the right side.  I can email a two page
X	troff output file that demonstrates the problem.
XFix:
X	Remove the assignment to pendingmove in CATForw() under
X	the PPROC case.

XSubject: box rule poorly defined in pscat.pro
XIndex:	lib/ps/pscat.pro 4.2BSD

XDescription:
X	The box rule defined in pscat.pro doesn't line up properly
X	with the underrule.  As a result, boxed tables generated
X	by tbl are incorrect.
XRepeat-By:
X	Use tbl to generate a boxed table.

XSubject: width of box rule incorrectly specified
XIndex:	lib/ps/troff.font/Times.map 4.2BSD

XDescription:
X	Times.map incorrectly defines the width of the box rule as

X	in the standard troff width tables).
XRepeat-By:
X	Use tbl to generate tables with vertical rules.  Observe
