|

|

;;
|
||
;; `texinfo-multitable' reads the @multitable line and determines from it
|
||
;; how wide each column should be.
|
||
;;
|
||
;; Also, it pushes this information, along with an identifying symbol,
|
||
;; onto the `texinfo-stack'. At the @end multitable command, the stack
|
||
;; is checked for its matching @multitable command, and then popped, or
|
||
;; else an error is signaled. Also, this command pushes the location of
|
||
;; the start of the table onto the stack.
|
||
;;
|
||
;; `texinfo-end-multitable' checks the `texinfo-stack' that the @end
|
||
;; multitable truly is ending a corresponding beginning, and if it is,
|
||
;; pops the stack.
|
||
;;
|
||
;; `texinfo-multitable-widths' is called by `texinfo-multitable'.
|
||
;; The function returns a list of the widths of each column in a
|
||
;; multi-column table, based on the information supplied by the arguments
|
||
;; to the @multitable command (by arguments, I mean the text on the rest
|
||
;; of the @multitable line, not the remainder of the multi-column table
|
||
;; environment).
|
||
;;
|
||
;; `texinfo-multitable-item' formats a row within a multicolumn table.
|
||
;; This command is executed when texinfmt sees @item inside @multitable.
|
||
;; Cells in row are separated by `@tab's. Widths of cells are specified
|
||
;; by the arguments in the @multitable line. Cells are filled. All cells
|
||
;; are made to be the same height by padding their bottoms, as needed,
|
||
;; with blanks.
|
||
;;
|
||
;; `texinfo-multitable-extract-row' is called by `texinfo-multitable-item'.
|
||
;; This function returns the text in a multitable row, as a string.
|
||
;; The start of a row is marked by an @item and the end of row is the
|
||
;; beginning of next @item or beginning of the @end multitable line.

A multi-column table has this template:
|

|

@multitable {A1} {A2} {A3}
|
||
@item A1 @tab A2 @tab A3
|
||
@item B1 @tab B2 @tab B3
|
||
@item C1 @tab C2 @tab C3
|
||
@end multitable
|

where the width of the text in brackets specifies the width of the
|
||
respective column.
|
||
|
||
Or else:
|
||
|
||
@multitable @columnfractions .25 .3 .45
|
||
@item A1 @tab A2 @tab A3
|
||
@item B1 @tab B2 @tab B3
|

@end multitable
|

where the fractions specify the width of each column as a percent
|
||
of the current width of the text (i.e., of the `fill-column').
|
||
|
||
Long lines of text are filled within columns.
|
||
|
||
Using the Emacs Lisp formatter, texinfmt.el,
|

the whitespace between columns can be increased by setting
|
||
`texinfo-extra-inter-column-width' to a value greater than 0. By default,
|
||
there is at least one blank space between columns.
|

|

The Emacs Lisp formatter, texinfmt.el, ignores the following four
|
||
commands that are defined in texinfo.tex for printed output.

@multitableparindent,

|

;; must follow the command name with two commas in a row; otherwise,
|

;; the Info formatting commands will misinterpret the end delimiter

|

|

;; to define `@phoo' as an Info formatting command that inserts `//'
|
||
;; before and `\\' after the argument to `@phoo'. You can then write
|
||
;; `@phoo{bar}' wherever you want `//bar\\' highlighted in Info.
|
||
;;
|
||
;; Also, for TeX formatting, you could write

;;
|
||
;; @iftex
|
||
;; @global@let@phoo=@i
|

;; @end iftex

|

;; In the original version, include files were ignored by Info but
|

;; incorporated in to the printed manual. To make references to the
|
||
;; included file, the Texinfo source file has to refer to the included
|
||
;; files using the `(filename)nodename' format for referring to other
|
||
;; Info files. Also, the included files had to be formatted on their
|
||
;; own. It was just like they were another file.
|
||
|
||
;; Currently, include files are inserted into the buffer that is
|
||
;; formatted for Info. If large, the resulting info file is split and
|
||
;; tagified. For current include files to work, the master menu must
|
||
;; refer to all the nodes, and the highest level nodes in the include
|
||
;; files must have the correct next, prev, and up pointers.
|
||
|
||
;; The included file may have an @setfilename and even an @settitle,
|
||
;; but not an `\input texinfo' line.
|
||
|
||
;; Updated 24 March 1993
|
||
;; In order for @raisesections and @lowersections to work, included
|
||
;; files must be inserted into the buffer holding the outer file
|
||
;; before other Info formatting takes place. So @include is no longer
|
||
