Rowspan in simple tables

Questions answered by this recipe

All sections are optional, you can remove those that do not apply to your recipe, and add new ones.

1. How do I specify that a cell spans 2 or more rows in a simple table?
2. How do I lay out a simple table so that a later editor can see the scope of a rowspan?
3. How do I lay out a simple table so that a later editor can see the scope of a colspan?

Description

Extend simple table markup to support a rowspan.

Installation

For PmWiki 2.3.37 or newer, the function is enabled by default. To disable it, add to config.php:

  $EnableSimpleTableRowspan = 0; # disable rowspan

For PmWiki 2.2.119 to 2.3.36, add to config.php:

  $EnableSimpleTableRowspan = 1; # enable rowspan

For PmWiki 2.2.118 or older:

• download rowspan.phpΔ or (for PHP 5.5 and above) rowspan55.phpΔ or (for PHP 5.0-7.2) rowspan72.phpΔ
• add the following line to local/config.php
  include_once("$FarmD/cookbook/rowspan.php");

Usage

The markup ||cell text+++ || adds rowspan="3" to the cell. The number of plus signs (+) defines the number of rows spanned. There must be 2 or more plus signs.

The markup ||____|| has the same effect as the markup ||||, 2 or more underscores (_) are required.

The markup ||^^^^|| has the same effect as the markup ||, 2 or more circumflex accents (^) are required.

That's all. It just works.

Notes

Simple tables can be hard to read. The recipe provides 2 simple table markup options with the sole purpose of making the table easier to edit. They have no effect whatsoever on the output. Their usage is entirely optional. Adding or removing them will not change the output.

Make rowspan more visible

|| border=1
||Spanning rows++  ||Regular text ||
||^^^^^^^^^^^^^^^^^||More text    ||
||Plain old text   ||Text ends    ||
||Spanning rows    ||Without using visibility markup ++||
||First column     ||

Make colspan more visible

|| border=1
||Spanning columns    ||_____________||Regular text ||
||More Regular        ||More text    ||Still more   ||
||Spanning columns    ||||Without using visibility markup ||
||____________________||Is this meaningful in the first column? ||No||It's not ||
|| Combine both markups to span three columns (''text centered'') ||____________||||

Spanning rows and columns

|| border=1
||Spanning 3 rows and 2 columns+++ ||||Regular text in third and fourth columns||||
||^^^^^^^^^^^^^^^^||Second row ||Fourth column ||
||Third row       ||Fourth column  ||
||Spanning rows and columns++ ||||||Fourth column ||
||Without using visibility markup ||
