.SH DESCRIPTION
|
||
|
|
This manual page describes the GNU version of
|
||
|
|
.BR tbl ,
|
||
|
|
which is part of the groff document formatting system.
|
||
|
|
.B tbl
|
||
|
|
compiles descriptions of tables embedded within
|
||
|
|
.B troff
|
||
|
|
input files into commands that are understood by
|
||
|
|
.BR troff .
|
||
|
|
Normally, it should be invoked using the
|
||
|
|
.B \-t
|
||
|
|
option of
|
||
|
|
.B groff.
|
||
|
|
It is highly compatible with Unix
|
||
|
|
.BR tbl .
|
||
|
|
The output generated by GNU
|
||
|
|
.B tbl
|
||
|
|
cannot be processed with Unix
|
||
|
|
.BR troff ;
|
||
|
|
it must be processed with GNU
|
||
|
|
.BR troff .
|
||
|
|
If no files are given on the command line, the standard input
|
||
|
|
will be read.
|
||
|
|
A filename of
|
||
|
|
.B \-
|
||
|
|
will cause the standard input to be read.
|
||
|
|
.SH OPTIONS
|

|
||
|

|
||
|
|
.SH USAGE
|
||
|
|
Only the differences between GNU
|
||
|
|
.B tbl
|
||
|
|
and Unix
|
||
|
|
.B tbl
|
||
|
|
are described here.
|
||
|
|
.LP
|
||
|
|
Normally
|
||
|
|
.B tbl
|
||
|
|
attempts to prevent undesirable breaks in the table by using diversions.
|
||
|
|
This can sometimes interact badly with macro packages' own use of diversions,
|
||
|
|
when footnotes, for example, are used.
|
||
|
|
The
|
||
|
|
.B nokeep
|
||
|
|
option tells
|
||
|
|
.B tbl
|
||
|
|
not to try and prevent breaks in this way.
|
||
|
|
.LP
|
||
|
|
The
|
||
|
|
.B decimalpoint
|
||
|
|
option specifies the character to be recognized as the decimal
|
||
|
|
point character in place of the default period.
|
||
|
|
It takes an argument in parentheses, which must be a single
|
||
|
|
character, as for the
|
||
|
|
.B tab
|
||
|
|
option.
|
||
|
|
.LP
|
||
|
|
The
|
||
|
|
.B f
|
||
|
|
format modifier can be followed by an arbitrary length
|
||
|
|
font name in parentheses.
|
||
|
|
.LP
|
||
|
|
There is a
|
||
|
|
.B d
|
||
|
|
format modifier which means that a vertically spanning entry
|
||
|
|
should be aligned at the bottom of its range.
|
||
|
|
.LP
|
||
|
|
There is no limit on the number of columns in a table, nor any limit
|
||
|
|
on the number of text blocks.
|
||
|
|
All the lines of a table are considered in deciding column
|
||
|
|
widths, not just the first 200.
|
||
|
|
Table continuation
|
||
|
|
.RB ( .T& )
|
||
|
|
lines are not restricted to the first 200 lines.
|
||
|
|
.LP
|
||
|
|
Numeric and alphabetic items may appear in the same column.
|
||
|
|
.LP
|
||
|
|
Numeric and alphabetic items may span horizontally.
|
||
|
|
.LP
|
||
|
|
.B tbl
|
||
|
|
uses register, string, macro and diversion names beginning with
|
||
|
|
.BR 3 .
|
||
|
|
When using
|
||
|
|
.B tbl
|
||
|
|
you should avoid using any names beginning with a
|
||
|
|
.BR 3 .
|
||
|
|
.SH BUGS
|
||
|
|
You should use
|
||
|
|
.BR .TS\ H / .TH
|
||
|
|
in conjunction with a supporting macro package for
|
||
|
|
.I all
|
||
|
|
multi-page boxed tables.
|
||
|
|
If there is no header that you wish to appear at the top of each page
|
||
|
|
of the table, place the
|
||
|
|
.B .TH
|
||
|
|
line immediately after the format section.
|
||
|
|
Do not enclose a multi-page table within keep/release macros,
|
||
|
|
or divert it in any other way.
|
||
|
|
.LP
|
||
|
|
A text block within a table must be able to fit on one page.
|
||
|
|
.LP
|
||
|
|
The
|
||
|
|
.B bp
|
||
|
|
request cannot be used to force a page-break in a multi-page table.
|
||
|
|
Instead, define
|
||
|
|
.B BP
|
||
|
|
as follows
|
||
|
|
.IP
|
||
|
|
.B .de BP
|
||
|
|
.br
|
||
|
|
.B .ie '\e\en(.z'' .bp \e\e$1
|
||
|
|
.br
|
||
|
|
.B .el \e!.BP \e\e$1
|
||
|
|
.br
|
||
|
|
.B ..
|
||
|
|
.br
|
||
|
|
.LP
|
||
|
|
and use
|
||
|
|
.B BP
|
||
|
|
instead of
|
||
|
|
.BR bp .
|
||
|
|
.LP

|
|
Using \ea directly in a table to get leaders will not work.
|
||
|
|
This is correct behaviour: \ea is a
|
||
|
|
.B uninterpreted
|
||
|
|
leader.
|
||
|
|
To get leaders use a real leader, either by using a control A or like
|
||
|
|
this:

||
|
|
.IP
|
||
|
|
.nf
