TBL(1) — Unix Programmer’s Manual
NAME
tbl − format tables for nroff or troff
SYNOPSIS
tbl [ files ] ...
DESCRIPTION
tbl is a preprocessor for formatting tables for nroff or troff(1). 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. For more information, see the tbl(1) reference manual.
If no arguments are given, tbl reads the standard input. This means you can use it as a filter. When using tbl with eqn or neqn, place the tbl command first to minimize the volume of data passed through pipes.
