---+ 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{...}%=

---++ 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 YYY - hh:mm
		* 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

---++ <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 sortable:
		* #Set SORT = attachments
		* Set SORT = all
		* #Set SORT = none

	* Default table attributes:
		* Set TABLEATTRIBUTES = tableborder="1" cellpadding="0" cellspacing="1" headerbg="#99CCCC" databg="#FFFFCC, #FFFFFF"


---++ 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{...}%=:

| *Argument* | *Comment* | *Example* |
| =sort=	  | Set table sorting ="on"= or ="off"= | =sort="on"= |
| =initsort= | Column to sort initially (="1"= to number of columns) | =initsort="2"= |
| =initdirection= | Initial sorting direction for =initsort=, set to  ="up"= or ="down"= | =initdirection="up"= |
| =headerbg= | Header cell background colour. Choose one of the %TWIKIWEB%.StandardColors | =headerbg="#99CCCC"= |
| =headercolor= | Header cell text colour | =headercolor="#0000CC"= |
| =databg=	| Data cell background colour, a comma separated list. Specify ="none"= for no colour, that is to use the colour/background of the page the table is on. | =databg="#C8CB8F, #DBDDB5"= |
| =datacolor= | Data cell text colour, a comma separated list | =datacolor="#0000CC, #000000"= |
| =tableborder= | Table border width (pixels) | =tableborder="2"= |
| =tableframe= | Table frame, set to ="void"= (no sides), ="above"= (the top side only), ="below"= (the bottom side only), ="hsides"= (the top and bottom sides only), ="lhs"= (the left-hand side only), ="rhs"= (the right-hand side only), ="vsides"= (the right and left sides only), ="box"= (all four sides), ="border"= (all four sides); default ="void"= | =tableframe="hsides"= |
| =tablerules= | Table rules, set to ="none"= (no rules), ="groups"= (rules will appear between row groups and column groups only), ="rows"= (rules will appear between rows only), ="cols"= (rules will appear between columns only), ="all"= (rules will appear between all rows and columns); default ="none"= | =tablerules="rows"= |		  
| =cellpadding= | Cell padding (pixels) | =cellpadding="0"= |
| =cellspacing= | Cell spacing (pixels) | =cellspacing="3"= |
| =valign= | Vertical alignment of cells, set to ="top"=, ="middle"=, ="bottom"= or ="baseline"= | =valign="top"= |
| =headeralign= | Header cell alignment, one value for all columns, or a comma separated list for different alignment of individual columns. Set to ="left"=, ="center"=, ="right"= or ="justify"=. Overrides individual cell settings | =headeralign="left, right"= |
| =dataalign= | Data cell alignment, one value for all columns, or a comma separated list for different alignment of individual columns. Set to ="left"=, ="center"=, ="right"= or ="justify"=. Overrides individual cell settings | =dataalign="center"= |
| =tablewidth= | Table width: Percentage of window width, or absolute pixel value. Default is unspecified | =tablewidth="100%"= |
| =columnwidths= | Column widths: Comma delimited list of column widths, percentage or absolute pixel value. Default is unspecified | =columnwidths="80%, 20%"= |
| =headerrows= | Number of header rows to exclude from sort; default ="1"= | =headerrows="1"= |
| =footerrows= | Number of footer rows to exclude from sort; default ="0"= | =footerrows="1"= |

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