You can specify column width (see examples on tbl(1) man page):
for example.  I don't know of the (1i) could be replaced with
(w'string') instead, but suspect it would work.  I've never needed
the feature in my stuff, so I don't know.

the  inter-column  space  seems  to be zero, i.e. in a table
with all left centered columns the longest entry (max. width
entry,  I  mean)  in  each column "touches" the neighbouring
entry in the same row (in the next column),  i.e.  it  looks
something like this, for instance:

a  b

if  column  1 has entries 'a' and 'foo' and column 2 'b' and
'bar'.  which sure it should not.

I was not lucky in the docs and the mail archive. so:

question  1:  is  there  a  way  to specify the inter-column
spacing (minimal distance between end of some entry and next
entry in the same row)? a register I should know of, e.g.?

question  2:  I have'nt seen this behaviour in the past. how
come?  has there been a change of default behaviour or am  I
doing something wrong which only surfaced now?


PS: I'm using `tbl' in conjunction with the `ms' macros and
groff version 1.19.3 under MacOS.

according to Murphy's law, I always discover something _after_ hitting
"send": my problem seems simply to be caused by mismatch between table
width and line length: the table in question was extending farther to
the right than it should. so quickly forget about my previous mail as
far as apparent misbehaviour of `tbl' is concerned. sorry for the noise.

but  I  still  would appreciate to get some hint how to tune
the inter-column spacing.

and it's still funny: the table is rendered completely (but extending
into the right margin), only the inter-column space is squeezed to zero,
it seems. now: is _this_ intended behaviour? should one not get some
kind of warning ("table to wide" or something like that)?
