NAME
tbl - format tables for nroff or troff
SYNOPSIS
tbl [ -TX ] [ files ]
DESCRIPTION
Tbl is a preprocessor that formats tables for nroff or troff (not
included on the UNIX PC). 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 re-formatted by tbl.
(The .TS and .TE command lines are not altered by tbl) .
• TS is followed by global options. The available global options
are:
center center the table (default is left-adjust);
expand make the table as wide as the current line
length;
box enclose the table in a box;
doublebox
enclose the table in a double box;
allbox enclose each item of the table in a box;
tab (x) use the character x instead of a tab to
separate items in a line of input data.
The global options, if any, are terminated with a semi-colon (;).
Next come lines describing the format of each line of the table.
Each such format line describes one line of the actual table, except
that the last format line (which must end with a period) describes
all remaining lines of the table. Each column of each line of the
table is described by a single key-letter, optionally followed by
specifiers that determine the font and point size of the corresponding
item, that indicate where vertical bars are to appear between
columns, that determine column width, inter-column spacing, etc.
The available key-letters are:
e center item within the column;
r right-adjust item within the column;
I left-adjust item within the column;
n numerically adjust item in the column: units positions
of numbers are aligned vertically;
s span previous item on the left into this column;
a center longest line in this column and then leftadjust
all other lines in this column with respect
to that centered line;
span down previous entry in this column;
replace this entry with a horizontal line;
replace this entry with a double horizontal line.
The characters B and I stand for the bold and italic fonts, respectively;
the character 1 indicates a vertical line between columns.
The format Jines are followed by lines containing the actual data
for the table, followed finally by .TE. Within such data lines,
data items are normally separated by tab characters.
