---+ Table Plugin

Gives extra control of table display:
	* Allows sorting
	* Changing table properties like border width, cell spacing and cell padding
	* Changing background color and text color for header cells
	* Changing background color and text color for data cells - colors can _alternate_
	* Table attributes can be set and overridden in this order:
		* Default =TABLEATTRIBUTES= Plugin setting in this topic.
		* A =TABLEATTRIBUTES= preferences setting on site-level (%TWIKIWEB%.TWikiPreferences) or web-level (any WebPreferences), e.g.
			* =Set TABLEATTRIBUTES = tableborder="0" cellpadding="1" ...=
		* Before a table using =%<nop>TABLE{...}%=
   * Row spans

---++ Sorting

Click on column heading text to sort by a column.  Initial column will be sorted in descending order, click again to get ascending order.  The type of data in the cell is determined automatically:

	* date if format is:
		* dd MMM YYYY - hh:mm (MMM is Jan, Feb, etc.)
		* dd-MMM-YY or dd-MMM-YYYY (can be / or space in place of -) (MMM is Jan, Feb, etc)
	* number is digits, with optional decimal point
	* otherwise treated as text

---++ Row spans

Table cells with a single caret indicate follow-up rows of multi-row spans. For example,
<table width="100%"><tr><td>
<verbatim>
| One One | One Two | One Three |
| ^ | Two Two | Two Three |
| Three One | ^ | Three Three |
</verbatim>
</td><td align="right">
| One One | One Two | One Three |
| ^ | Two Two | Two Three |
| Three One | ^ | Three Three |
</td></tr></table>

---++ <nop>%TOPIC% Global Settings

Plugin settings are stored as preferences variables. To reference
a plugin setting write ==%<nop>&lt;plugin&gt;_&lt;setting&gt;%==, for example, ==%<nop>INTERWIKIPLUGIN_SHORTDESCRIPTION%==

	* One line description, shown in the %TWIKIWEB%.TextFormattingRules topic:
		* Set SHORTDESCRIPTION = Control attributes of tables and sorting of table columns

	* Set DEBUG to 1 to get debug messages in =data/debug.txt=.  Default: =0=
		* Set DEBUG = 0

	* Make all tables in a topic sortable. If this is set to =all=, all tables that have a header row (including those that do not have %TABLE before them) will be made sortable. If set to =none=, only tables with %TABLE will be sortable. Topic rendering is faster if this is set to =none=.
		* #Set SORT = none
		* Set SORT = all

	* Default table attributes:
		* Set TABLEATTRIBUTES = tableborder="1" cellpadding="0" cellspacing="0" valign="top" headercolor="#ffffff" headerbg="#687684" headerbgsorted="#334455" databg="#ffffff,#edf4f9" databgsorted="#f1f7fc,#ddebf6" tablerules="rows"

---++ Table Attributes

Attributes are defined as a =TABLEATTRIBUTES= Plugin setting in this topic, a =TABLEATTRIBUTES= preferences setting, or on line before the table using =%<nop>TABLE{...}%=:
%INCLUDE{"%TWIKIWEB%.VarTABLE" section="table_attributes"}%

The =%<nop>TABLE{...}%= settings override =TABLEATTRIBUTES= preferences settings, which override the =TABLEATTRIBUTES= Plugin settings. 

The setting =disableallsort= is normally not used as a TABLE or TABLEATTRIBUTES setting. Plugins such as EditTablePlugin dynamically sets =disableallsort= to disable sorting while editing a table. For this to work it is important that EditTablePlugin runs before TablePlugin, which is the default. The setting =sort= can be overwritten by a URL parameter or hidden formfield of the same name. Plugins such as EditTablePlugin can use this to disable table header sorting while in edit mode.

---++ Examples

---+++ Use of %<nop>TABLE{...}%

Line before table: =%<nop>TABLE{ sort="on" tableborder="0" cellpadding="4" cellspacing="3" cellborder="0" headerbg="#D5CCB1" headercolor="#666666" databg="#FAF0D4, #F3DFA8" headerrows="2" footerrows="1" }%=

%TABLE{ sort="on" tableborder="0" cellpadding="4" cellspacing="3" cellborder="0" headerbg="#D5CCB1" headercolor="#666666" databg="#FAF0D4, #F3DFA8" headerrows="2" footerrows="1" }%

---++ !TablePlugin and CSS
Information for programmers.

!TablePlugin implements the following precedence:
   * the =TABLEATTRIBUTE= settings only write html styling, no CSS
   * the =TABLEATTRIBUTE= settings can be overridden by a skin's CSS
   * the =TABLE= tag attributes are converted to CSS styling, written in the head; these override any skin's CSS
    
---+++ CSS written by !TablePlugin
|=.twikiTable=  |The table  |
|=.twikiSortedCol=  |A sorted column  |
|=.twikiSortedAscendingCol=  |Sorted column, ascending  |
|=.twikiSortedDescendingCol=  |Sorted column, descending  |
|=.tableSortIcon=  |The sort icon holder (span)  |
|=.twikiFirstCol=  |The first column  |
|=.twikiTableEven= |Even numbered rows  |
|=.twikiTableOdd= |Odd numbered rows  |
|=.twikiTableCol= + column number  | Unique column identifier, for instance: =twikiTableCol0= |
|=.twikiTableRow= + type + row number | Unique row identifier, for instance: =twikiTableRowdataBg0= |


---++ Plugin Installation Instructions
This plugin is pre-installed with your TWiki release. You should not have to install it other than to do an upgrade.

	* Download the ZIP file from the Plugin web (see below)

|  Plugin Version: | 1.036 (01 Oct 2008) |
|  Change History: | <!-- specify latest version first -->&nbsp; |
|  30 Sep 2008 | 1.035 Fix sorting of attachment date column.  |
|  03 Aug 2008 | 1.034 TWiki 4.2.1 release version |
|  20 Mar 2008 | 1.033 TWikibug:Item5387: allow rowspanned columns to contain HTML tags; otherwise it is impossible to add an invisible anchor to a rowspanned cell |
|  16 Dec 2007 | 1.030: Kenneth Lavrsen: Fixed the problem of tables being sorted by by TablePlugin while the table is being edited by plugins such as EditTablePlugin. This required adding a new attribute =disableallsort= so plugins such as EditTablePlugin can temporarily disable all sorting for a table. Additionally the CGI variable (URL parameter or hidden formfield) =sort= can be set to "off" which disables all header sorting in the topic. This is used by plugins such as EditTablePlugin to disable the sorting by clicking header fields during editing of tables. Ref: TWikibug:Item5135 and TWikibug:Item2690. |
|  03 Dec 2007 | Arthur Clemens: Fixed rendering and order of html elements =thead=, =tfoot= and =tbody=; corrected =id= parameter. |
