.Sh DESCRIPTION
|
|
The
|
|
.Nm tbl
|
|
language is a table-formatting language.
|
|
It is used within
|
|
.Xr mdoc 7
|
|
and
|
|
.Xr man 7
|
|
.Ux
|
|
manual pages.
|
|
This manual describes the subset of the
|
|
.Nm
|
|
language accepted by the
|
|
.Xr mandoc 1
|
|
utility.
|
|
.Pp
|
|
Tables within
|
|
.Xr mdoc 7
|
|
or
|
|
.Xr man 7
|
|
are enclosed by the
|
|
.Sq TS
|
|
and
|
|
.Sq TE
|
|
macro tags, whose precise syntax is documented in
|
|
.Xr roff 7 .
|
|
Tables consist of a series of options on a single line, followed by the
|
|
table layout, followed by data.
|
|
.Pp
|
|
For example, the following creates a boxed table with digits centred in
|
|
the cells.
|
|
.Bd -literal -offset indent
|
|
\&.TS
|
|
tab(:) box;
|
|
c5 c5 c5.
|
|

|
|
4:5:6
|
|
\&.TE
|
|
.Ed
|
|
.Pp
|
|
When formatted, the following output is produced:
|
|
.Bd -filled -offset indent -compact
|
|
.TS
|
|
tab(:) box;
|
|
c5 c5 c5.

Tables are enclosed by the

.Sq TS
|
|
and
|
|
.Sq TE
|
|
.Xr roff 7
|
|
macros.
|
|
A table consists of an optional single line of table
|
|
.Sx Options
|
|
terminated by a semicolon, followed by one or more lines of
|
|
.Sx Layout
|
|
specifications terminated by a period, then
|
|
.Sx Data .
|
|
All input must be 7-bit ASCII.
|
|
Example:
|
|
.Bd -literal -offset indent
|

Table data is
|
|
.Em pre-processed ,
|
|
that is, data rows are parsed then inserted into the underlying stream
|
|
of input data.
|
|
This allows data rows to be interspersed by arbitrary
|
|
.Xr roff 7 ,
|
|
.Xr mdoc 7 ,
|
|
and
|
|

|
|
.Ss Options
|
|
The first line of a table consists of space-separated option keys and
|
|
modifiers terminated by a semicolon.
|
|
If the first line does not have a terminating semicolon, it is assumed
|
|
that no options are specified and instead a
|
|
.Sx Layout
|
|
is processed.
|
|
Some options accept arguments enclosed by parenthesis.
|
|
The following case-insensitive options are available:
|
|
.Bl -tag -width Ds
|
|
.It Cm center
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
This may also be invoked with
|
|
.Cm centre .
|
|
.It Cm delim
|
|
Accepts a two-character argument.
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.It Cm expand
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.It Cm box
|
|
Draw a single-line box around the table.
|
|
This may also be invoked with
|
|
.Cm frame .
|
|
.It Cm doublebox
|
|
Draw a double-line box around the table.
|
|
This may also be invoked with
|
|
.Cm doubleframe .
|
|
.It Cm allbox
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.It Cm tab
|
|
Accepts a single-character argument.
|
|
This character is used as a delimiter between data cells, which otherwise
|
|
defaults to the tab character.
|
|
.It Cm linesize
|
|
Accepts a natural number (all digits).
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.It Cm nokeep
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.It Cm decimalpoint
|
|
Accepts a single-character argument.
|
|
This character will be used as the decimal point with the
|
|
.Cm n
|
|
layout key.
|
|
.It Cm nospaces
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.El
|
|
.Ss Layout
|
|
The table layout follows
|
|
.Sx Options
|
|
or a
|
|
.Sq \&T&
|
|
macro invocation.
|
|
Layout specifies how data rows are displayed on output.
|
|
Each layout line corresponds to a line of data; the last layout line
|
|
applies to all remaining data lines.
|
|
Layout lines may also be separated by a comma.
|
|
Each layout cell consists of one of the following case-insensitive keys:
|
|
.Bl -tag -width Ds
|
|
.It Cm c
|
|
Centre a literal string within its column.
|
|
.It Cm r
|
|
Right-justify a literal string within its column.
|
|
.It Cm l
|
|
Left-justify a literal string within its column.
|
|
.It Cm n
|
|
Justify a number around its last decimal point.
|
|
If the decimal point is not found on the number, it's assumed to trail
|
|
the number.
|
|
.It Cm s
|
|
Horizontally span columns from the last
|
|
.No non- Ns Cm s
|
|
data cell.
|
|
It is an error if spanning columns follow a
|
|
.Cm \-
|
|
or
|
|
.Cm \(ba
|
|
cell, or come first.
|
|
This option is not supported by
|
|
.Xr mandoc 1 .
|
|
.It Cm a
|
|
Left-justify a literal string and pad with one space.
|
|
.It Cm ^
|
|
Vertically span rows from the last
|
|
.No non- Ns Cm ^
|
|
data cell.
|
|
It is an error to invoke a vertical span on the first layout row.
|
|
Unlike a horizontal spanner, you must specify an empty cell (if it not
|
|
empty, the data is discarded) in the corresponding data cell.
|
|
.It Cm \-
|
|
Replace the data cell (its contents will be lost) with a single
|
|
horizontal line.
|
|
This may also be invoked with
|
|
.Cm _ .
|
|
.It Cm =
|
|
Replace the data cell (its contents will be lost) with a double
|
|
horizontal line.
|
|
.It Cm \(ba
|
|
Emit a vertical bar instead of data.
|
|
.It Cm \(ba\(ba
|
|
Emit a double-vertical bar instead of data.
|
|
.El
|
|
.Pp
|
|
Keys may be followed by a set of modifiers.
|
|
A modifier is either a modifier key or a natural number for specifying
|
|
the minimum width of a column.
|
|
The following case-insensitive modifier keys are available:
|
|
.Cm z ,
|
|
.Cm u ,
|
|
.Cm e ,
|
|
.Cm t ,
|
|
.Cm d ,
|
|
.Cm b ,
|
|
.Cm i ,
|
|
.Cm r ,
|
|
and
|
|
.Cm f
|
|
.Po
|
|
followed by
|
|
.Cm b ,
|
|
.Cm i ,
|
|
.Cm r ,
|
|
.Cm 3 ,
|
|
.Cm 2 ,
|
|
or
|
|
.Cm 1
|
|
.Pc .
|
|
All of these are ignored by
|
|
.Xr mandoc 1 .
|
|
.Pp
|
|
For example, the following layout specifies a centre-justified column of
|
|
minimum width 10, followed by vertical bar, followed by a left-justified
|
|
column of minimum width 10, another vertical bar, then a column
|
|
justified about the decimal point in numbers:
|
|
.Pp
|
|
.Dl c10 | l10 | n
|
|
.Ss Data
|
|
The data section follows the last layout row.
|
|
By default, cells in a data section are delimited by a tab.
|
|
This behaviour may be changed with the
|
|
.Cm tab
|
|
option.
|
|
If
|
|
.Cm _
|
|
or
|
|
.Cm =
|
|
is specified, a single or double line, respectively, is drawn across the
|
|
data field.
|
|
If
|
|
.Cm \e-
|
|
or
|
|
.Cm \e=
|
|
is specified, a line is drawn within the data field (i.e. terminating
|
|
within the cell and not draw to the border).
|
|
If the last cell of a line is
|
|
.Cm T{ ,
|
|
all subsequent lines are included as part of the cell until
|
|
.Cm T}
|
|
is specified as its own data cell.
|
|
It may then be followed by a tab
|
|
.Pq or as designated by Cm tab
|
|
or an end-of-line to terminate the row.

In GNU tbl, comments and macros are disallowed prior to the data block

.Sh HISTORY
|
|
The tbl utility, a preprocessor for troff, was originally written by M.
|
|
E. Lesk at Bell Labs in 1975.
|
|
The GNU reimplementation of tbl, part of the groff package, was released
|
|
in 1990 by James Clark.
|
|
A standalone tbl implementation was written by Kristaps Dzonsons in
|
|
2010.
|
|
This formed the basis of the implementation that is part of the
|
|
.Xr mandoc 1
|
|
utility.
