Description

This recipe will adds Directives and provides abilities for nested tables and for horizontal and vertical zebra tables.

A demo of the capabilities is at URL: http://gnuzoo.org/test/AdvancedTableDirectives

Two other recipes which enhance AdvancedTableDirectives are SourceCodeHorizontalLines and SimplifiedAdvancedTableDirectives.

Currently tables have 3 capabilities that table directives do not have. "<header>", "<caption>" and automatic zebra formatting (see FormattingTables) of rows and columns (there are probably others too). Table Directives cannot be nested and include only 4 directives. (:table:) (:cell:) (:cellnr:) (:tableend:)

This recipe will adds these directives:

(:caption:) - caption
(:head:)    - header cell
(:headnr:)  - header cell new row
(:row:)     - row

(:cellc#:)  - current column number
(:cellr#:)  - current row number

(:celli#:)  - auto-incrementing number - incremented when used
(:celli#1:) - (:celli#2:), ... (:celli#9:)]] - seperate auto-incrementing numbers

(:cellic#:) - auto-incrementing column number - incremented when used, set to 1 on new row
(:cellir#:) - auto-incrementing row number - incremented when used in a new row, but not in same row

Notes

All directives follow the same syntax: (: directive (attributes) :)

For example:

(:caption color=red :)This is the caption text
(:head bgcolor=lightblue :)This is header text

Automatic zebra formatting (mostly used for coloring) can be applied as well. In this example the table header row will have a lightblue background and the other table rows will have alternating lightgreen and lightyellow background colors.

$TableRowIndexMax = 2;
$TableRowAttrFmt  = "class='row\$TableRowIndex'" ;
$TableCellAttrFmt = "class='col\$TableCellCount'";

table th      { background-color:#99ccff; }
table tr.row1 { background-color:#ffff99 ; }
table tr.row2 { background-color:#ccffcc; }
table td      { line-height: 12px; }

For vertical zebra tables there are 2 new variables - TableCellIndexMax and $TableCellIndex

$TableCellIndexMax = 3;
$TableRowIndexMax = 2;
$TableRowAttrFmt  = "class='row\$TableRowIndex'" ;
$TableCellAttrFmt = "class='col\$TableCellCount colidx\$TableCellIndex'";

table td.colidx1 {background-color:#ffff99;}
table td.colidx2 {background-color:#ccffcc;}
table td.colidx3 {background-color:#FFC0CB;}

For more information about formatting tables see FormattingTables.

About Merging Attributes

Attributes can automatically be placed onto directives using $TableCellAttrFmt and/or $TableRowAttrFmt. This can conflict with attributes specified directly on the directive itself. (This is one of several reasons normal Table Directives dot not use $TableCellAttrFmt and/or $TableRowAttrFmt). This recipe will merge only the class element - meaning it will eliminate duplicates and setup multiple class attributes as a space separated string (like this - class='classname1 classname2 classname3' - per W3C recommendation). I have chosen not to merge other attributes because it would make the code very complicated and slower and most other attributes can be set in a cascading style sheet. Any attributes besides class that are designated in $TableCellAttrFmt and/or $TableRowAttrFmt are simply appended to the directive attributes and not merged.

Comments

I don't know what I'm doing wrong, but I keep getting the following error:

      "Warning: Cannot modify header information - headers already sent by (output started 
      at /home/<MySite>/public_html/pmwiki-2.1.26/cookbook/AdvancedTableDirectives.php:195) 
      in /home/<MySite>/public_html/pmwiki-2.1.26/pmwiki.php on line 884"

I have tried this with an existing wiki and a clean install (no other cookbook recipes installed).
Any ideas? I will be happy to supply more information if needed.
Thank you!

Thanks, that did it! Kevin Jackson 09/19/2006

Very nice recipe, thank you! H. 26/10/2006

This recipe clashes with ZAP : I was in trouble when trying using this really nice recipe with zap forms ! Adding : $RecipeRunAction[$RecipeName][]='zap'; in the php file did the trick (or seemed to ..). I suspect that the same kind of clash will occur with every package that adds an action to the list.
