.NXA "nroff text processor" "tbl preprocessor"
.NXR "table" "formatting"
The
.PN tbl
preprocessor is used for formatting tables for
.PN nroff

.PN *roff .
The input files are copied to the standard output,
except for lines between .TS and .TE command lines,
which are assumed to describe tables
and are reformatted.
.SH Options
.IP \-TX 8
Produces output without fractional line motions.
Use when the destination output device or
printer or post-filter cannot handle fractional line motions.
.IP \-ms
Reads in 
.PN ms
macros prior to table formatting.
.IP \-mm
Reads in the 
.PN mm 
macros prior to table formatting, if your system
has the 
.PN *roff 
.PN mm 
macros installed.

If no arguments are given,
.PN tbl
reads the standard input, so it may be used as a filter.  When 
.PN tbl
is used with
.PN eqn
or
.PN neqn ,
.NXR "tbl preprocessor" "eqn and"
the
.PN tbl
command should be first, to minimize the volume of data passed through pipes.
