     tbl - format tables for nroff or troff


     tbl [ files ] ...


     Tbl is an nroff (I) or troff(I) preprocessor for  formatting

     tables.   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 reformatted.  The first

     line after .TS specifies the various columns: it consists of

     a  list  of  column  describers separated by blanks or tabs.

     Each column describer is a character string made up  of  the

     letters `n', `r', `c', `l' and `s', which mean:

     c    center within the column

     r    right-adjust

     l    left-adjust

     n    numerical adjustment: the units digits of  numbers  are


     s    span the previous entry over this column.

     The column describer may be followed by  an  integer  giving

     the  number of spaces between this column and the next; 3 is

     default.  The describer `ccr5' indicates that the first  two

     lines  in  this column are centered; the third and remaining

     lines are right-adjusted; and the column should be separated

     from  the  column  to  the  right  by  5 spaces.  Letting \t

     represent a tab (which must be typed as a genuine  tab)  the

     If no arguments are given, tbl reads the standard input,  so

     it  may  be  used  as a filter.  When it is used with eqn or

     neqn the tbl command should be first, to minimize the volume

     of data passed through pipes.


     No column describer may end with `s'.
