---+ 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" headeralign="center" headercolor="#ffffff" headerbg="#6b7f93" headerbgsorted="#334455" headercolor="#ffffff" databg="#ffffff,#edf4f9" databgsorted="#f5f5f5,#dce7ee"
		* Classic skin table attributes:
			* #Set TABLEATTRIBUTES = tableborder="1" cellpadding="0" cellspacing="1" headerbg="#99cccc" databg="#ffffff,#ffffcc"
