TBL(l) TBL( l)
NAME
tbl - prepare tables for nroff or troff
SYNOPSIS
tbl [ -T X ] [ -- ] [ files ] [ - ]
DESCRIPTION
tbl is a preprocessor that prepares tables for nroff( l) or troff. tbl assumes
that lines between the .TS and .TE command lines describe tables, thus
they are re-formatted; lines outside these command lines are copied to
the standard output. (tbl does not alter the .TS and .TE command lines.
Follow .TS with global options. The available global options are:
center
expand
box
double box
allbox
tab (x)
linesize ( n)
centers the table (default is left-adjust);
makes the table as wide as the current line
length;
encloses the table in a box;
encloses the table in a double box;
encloses each item of the table in a box;
uses the character x instead of a tab to
separate items in a line of input data.
sets line or rules (e.g., from box) in n-point
type;
End the global options, if any, with a semi-colon ( ;).
After global options come lines describing the format of each line of the
table. Each such format line describes one line of the table itself, except
that the last format line (which you must end with a period) describes all �
remaining lines of the table. A single key letter describes each column of
l
each line of the table. You may follow this key letter with specifiers that
determine the font and point size of the corresponding item, that indicate
where vertical bars are to appear between columns, and that determine
column width, inter-column spacing, etc. The available key-letters are:
c centers item within the column;
r right-adjusts item within the column;
I left-adjusts item within the column;
n numerically adjusts item in the column: units positions
of numbers are aligned vertically;
s spans previous item on the left into this column;
a centers longest line in this column and then left-adjust
all other lines in this column with respect to that centered
line;
A spans down previous entry in this column;
replaces this entry with a horizontal line;
= replaces this entry with a double horizontal line.
The characters B and I stand for the bold and italic fonts, respectively;
the character I indicates a vertical line between columns.
The format lines 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.
If a data line consists of only _ or =, a single or double line, respectively,
is drawn across the table at that point; if a single item in a data line consists
of only _ or =, then that item is replaced by a single or double line.
Some printers do not have the vertical resolution to produce double lines.
