How many times has this question been asked? This is relative to [di]troff, tbl, and eqn (as part of the DWB). Does anyone have any examples of incorporating equations (eqn) into tables (tbl) that they could send me? I haven't found any examples anywhere (I've checked the DWB documentation, I've checked the Dougherty and O'Reilly book, etc.). I've tried inline equations (without success). Any examples or suggestions welcome! Thanks, in advance. Bruce -- Bruce W. Mohler Systems Programmer (aka Staff Analyst) bruno@sdcc10.ucsd.edu voice: 619-586-2218

Here is a very short example using both in-line and displayed equations
inside a table.
This subject and much more -- PICtures in tables, tables in PICtures,
equations in PICtures in tables, tables in tables, and tables in
PICtures -- is explored in depth in TYPESETTING TABLES ON THE UNIX
SYSTEM, by Mary McNabb and Henry McGilton.

There are all kinds of caveats, and some examples. But that would be telling. Here's part of an example, though: .EQ delim $$ .EN .TS doublebox; cB cB 1 1. .sp 2p Name Definition .vs +2p Gamma $GAMMA (z)~=~int sub 0 sup inf t sup {z-1} e sup -t dt$ etc. .TE So, at least it can be done.

To be fair, so does the tbl documentation back at least as far as v7. (Sorry; I don't have anything earlier.:-) > There are all kinds of caveats, and some examples. > But that would be telling. Here's part of an example, though: [excerpt of example] Looks to be approximately the same example as in the 1979 paper by Lesk. No intent to flame Peter, but since most of us don't have (and can't get:-( DWB 3.x, a little software archaeology may be helpful. The equation- within-table example persists in BSD manuals to this day, although it may have been dropped from some of the AT&T manuals in the interregnum. -- Dick Dunn rcd@ico.isc.com -or- ico!rcd Boulder, CO (303)449-2870 ...But is it art?

When I preface any of my replies by "In DBW 3.1..." all I intend to say is "It works in DWB 3.1 and I'm too lazy to see if it also works in DWB 2.0, groff, SunOS troff, etc." I'll leave it to others to report whether older versions support a particular feature. I work in Bell Laboratories, not the Smithsonian, so I'm more interested in current and future developments than past. In this particular case, the original poster claimed to have searched all appropriate documentation with no success, and I took him at his word. As Dick indicates, *all* tbl documentation, no matter how old, seems to include the instruction to pipe tbl into eqn.

E. Quin lee@sq.com Most of the responses included actual examples. Some were plugs for books (which did not detract from the response). The books mentioned were: _An Introduction to Text Processing_, Peter Smith, MIT, 1990 _Typesetting Tables on the Unix System_, McNabb & McGilton, Trilithon Press My mentioning the books does not constitute a recommendation of them. Since most of the responses were by e-mail, I wanted to briefly summarize what I learned: * run eqn *before* tbl * don't forget the delim() commands in the tbl section * don't use '#' as an eqn delimiter * don't use '$' as an eqn delimiter if you're using troff macros with '$'s in them Here's a brief example: .EQ delim $$ .EN .TS box, center, tab(@), delim($$); l l . . . . .TE Note that delim defined for eqn first. Note also the "delim($$)" defined for tbl (that was *my* mistake). Again, thanks for your responses! Bruce -- Bruce W.
