Name
       tbl - format tables for nroff or *roff

Syntax
       tbl [files...]

Description
       The  preprocessor  is used for formatting tables for or 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.

Options
       -TX     Produces output without fractional line motions.  Use when the destination output device or printer or  post-filter  cannot  handle
	       fractional line motions.

       -ms     Reads in macros prior to table formatting.

       -mm     Reads in the macros prior to table formatting, if your system has the macros installed.

Examples
       As an example, letting 	 represent a tab (which should be typed as a genuine tab) the input

	      .TS
	      c s s
	      c c s
	      c c c
	      l n n.
	      Household Population
	      Town	Households
	      	Number	Size
	      Bedminster	789	3.26
	      Bernards Twp.	3087	3.74

	      Bridgewater	7897	3.81
	      Far Hills	240	3.19
	      .TE

       yields

		  Household Population
		  Town	       Households
			      Number   Size
	      Bedminster	789    3.26
	      Bernards Twp.    3087    3.74
	      Bernardsville    2018    3.30

	      Bridgewater      7897    3.81
	      Far Hills 	240    3.19

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