22 .Nd tbl language reference for mandoc
26 language is a table-formatting language.
33 This manual describes the subset of the
35 language accepted by the
47 macro tags, whose precise syntax is documented in
49 Tables consist of a series of options on a single line, followed by the
50 table layout, followed by data.
52 For example, the following creates a boxed table with digits centred in
54 .Bd -literal -offset indent
63 When formatted, the following output is produced:
64 .Bd -filled -offset indent -compact
73 Tables are enclosed by the
79 A table consists of an optional single line of table
81 terminated by a semicolon, followed by one or more lines of
83 specifications terminated by a period, then
85 All input must be 7-bit ASCII.
87 .Bd -literal -offset indent
99 that is, data rows are parsed then inserted into the underlying stream
101 This allows data rows to be interspersed by arbitrary
107 .Bd -literal -offset indent
121 .Bd -literal -offset indent
135 The first line of a table consists of space-separated option keys and
136 modifiers terminated by a semicolon.
137 If the first line does not have a terminating semicolon, it is assumed
138 that no options are specified and instead a
141 Some options accept arguments enclosed by parenthesis.
142 The following case-insensitive options are available:

168 Accepts a single-character argument.
169 This character is used as a delimiter between data cells, which otherwise
170 defaults to the tab character.
172 Accepts a natural number (all digits).

180 This character will be used as the decimal point with the
184 This option is not supported by
188 The table layout follows
193 Layout specifies how data rows are displayed on output.
194 Each layout line corresponds to a line of data; the last layout line
195 applies to all remaining data lines.
196 Layout lines may also be separated by a comma.
197 Each layout cell consists of one of the following case-insensitive keys:
200 Centre a literal string within its column.
202 Right-justify a literal string within its column.
204 Left-justify a literal string within its column.
206 Justify a number around its last decimal point.
207 If the decimal point is not found on the number, it's assumed to trail
210 Horizontally span columns from the last
213 It is an error if spanning columns follow a
218 This option is not supported by
221 Left-justify a literal string and pad with one space.
223 Vertically span rows from the last
226 It is an error to invoke a vertical span on the first layout row.
227 Unlike a horizontal spanner, you must specify an empty cell (if it not
228 empty, the data is discarded) in the corresponding data cell.
230 Replace the data cell (its contents will be lost) with a single
232 This may also be invoked with
235 Replace the data cell (its contents will be lost) with a double
238 Emit a vertical bar instead of data.
240 Emit a double-vertical bar instead of data.
243 Keys may be followed by a set of modifiers.
244 A modifier is either a modifier key or a natural number for specifying
245 the minimum width of a column.
246 The following case-insensitive modifier keys are available:
267 All of these are ignored by
270 For example, the following layout specifies a centre-justified column of
271 minimum width 10, followed by vertical bar, followed by a left-justified
272 column of minimum width 10, another vertical bar, then a column
273 justified about the decimal point in numbers:
277 The data section follows the last layout row.
278 By default, cells in a data section are delimited by a tab.
279 This behaviour may be changed with the
286 is specified, a single or double line, respectively, is drawn across the
292 is specified, a line is drawn within the data field (i.e. terminating
293 within the cell and not draw to the border).
294 If the last cell of a line is
296 all subsequent lines are included as part of the cell until
298 is specified as its own data cell.
299 It may then be followed by a tab
300 .Pq or as designated by Cm tab
301 or an end-of-line to terminate the row.
303 This section documents compatibility between mandoc and other
305 implementations, at this time limited to GNU tbl.
309 In GNU tbl, comments and macros are disallowed prior to the data block
313 implementation allows them.
323 .%T Tbl\(emA Program to Format Tables
327 The tbl utility, a preprocessor for troff, was originally written by M.
328 E. Lesk at Bell Labs in 1975.
329 The GNU reimplementation of tbl, part of the groff package, was released
330 in 1990 by James Clark.
331 A standalone tbl implementation was written by Kristaps Dzonsons in
333 This formed the basis of the implementation that is part of the
