tbl format tables for nroff or troff [ files ] ... 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 aligned. |
|
|
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.
