tbl(1) tbl(1)NAME tbl - format tables for nroff or troff SYNOPSIS tbl [-TX] [file...] DESCRIPTION tbl is a preprocessor that formats tables for nroff or troff. 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 by tbl. (The .TS and .TE command lines are not altered by tbl). .TS is followed by global options. The available global op- tions 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 semicolon (;). Next come lines describing the format of each line of the table. Each such format line describes one line of the ac- tual 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 sin- gle keyletter, optionally followed by specifiers that deter- mine the font and point size of the corresponding item, that indicate where vertical bars are to appear between columns, that determine column width, intercolumn spacing, etc. The available keyletters are: c center item within the column; r right adjust item within the column; l left adjust item within the column; n numerically adjust item in the column: units posi- tions of numbers are aligned vertically; s span previous item on the left into this column; a center longest line in this column and then left ad- just 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.

tbl(1) tbl(1)The characters B and I stand for the bold and italic fonts, respectively; the character | 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 charac- ters. 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. Full details of all these and other features of tbl are given in the reference manual cited below. The -TX flag option forces tbl to use only full vertical line motions, making the output more suitable for devices that cannot generate partial vertical line motions (for ex- ample, line printers). If no file names are given as arguments (or if - is speci- fied as the last argument), tbl reads the standard input, so it may be used as a filter. When it is used with eqn(1) or neqn, tbl should come first to minimize the volume of data passed through pipes.
