   .Ss \&TS
   Begin a table, which formats input in aligned rows and columns.
   A table consists of an optional single line of table options terminated
   by a semicolon, followed by one or more lines of layout specification
   terminated by a period, then table data.
   A table block may also include
   .Nm ,
   .Xr mdoc 7 ,
   or
   .Xr man 7
   macros.
   Example:
   .Bd -literal -offset indent
   \&.TS
   box tab(:);   \e" Table-wide options.
   c | c         \e" Layout for first line.
   | c | c.      \e" Layout for all subsequent lines.

   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 macros, such as
   .Bd -literal -offset indent
   \&.TS
   tab(:);
   c c c.

   The first line of a table consists of its options, which consists of
   space-separated 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 layout is processed.
   Some options accept arguments enclosed by paranthesis.
   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 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.
   This option is not supported by
   .Xr mandoc 1 .
   .It Cm nospaces
   This option is not supported by
   .Xr mandoc 1 .
   .El
   .Pp
   The table layout follows table options, except in the case of
   .Sx \&T& ,
   where it immediately procedes 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 decimal point.
   If the decimal point is not found on the number, it's assumed to trail
   the number.
   .It Cm s
   This option is not supported by
   .Xr mandoc 1 .
   .It Cm a
   This option is not supported by
   .Xr mandoc 1 .
   .It Cm ^
   This option is not supported by
   .Xr mandoc 1 .
   .It Cm \-
   This may also be invoked with
   .Cm _ .
   .It Cm =
   .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
   spacing.
   The following case-insensitive modifier keys are available:
   .Bl -tag -width Ds
   .It Cm z
   .It Cm u
   .It Cm e
   .It Cm t
   .It Cm d
   .It Cm f
   Must be followed by a case-insensitive font style:
   .Cm b
   for bold or
   .Cm i
   for italic.
   .It Cm b
   .It Cm i
