Table Plugin

Gives extra control of table display:

• Sorting
• Setting visual table properties like border width, cell spacing and cell padding
• Setting the background color and text color of header cells
• Setting the background color and text color for data cells, for instance to get an alternating zebra pattern
• Merging cells (row and col spans)

Table Attributes

Attributes are defined as a TABLEPLUGIN_TABLEATTRIBUTES preference, or on the line before the table using %TABLE{...}%:

Attributes for tables

Argument	Comment	Default value	Example

Specifying and overriding attributes

Table attributes can be set in different ways. In top down order:

1. As default preference in Configure.
2. As preference in a topic: TABLEPLUGIN_TABLEATTRIBUTES: Set TABLEPLUGIN_TABLEATTRIBUTES = tableborder="0" cellpadding="1" ...
3. As parameters to the TABLE macro: %TABLE{ tableborder="0" cellpadding="4" cellspacing="3" cellborder="0" }%

The preference TABLEPLUGIN_TABLEATTRIBUTES = ... competely overrides previous preferences (for example in Main.SitePreferences or Configure):

   * Set TABLEPLUGIN_TABLEATTRIBUTES = cellpadding="0" <<< this will remove previously set preferences and leave only 1 attribute

If you pass %TABLE{...}% parameters, you partially override previously set preferences:

   * %TABLE{datacolor="#f00"}% <<< this will only change the data color attribute

Reserved attributes

The setting disableallsort is normally not used as a TABLE or TABLEPLUGIN_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 %TABLE{...}%

Line before table:

%TABLE{ sort="on" tableborder="0" cellpadding="4" cellspacing="3" cellborder="0" headerbg="#D5CCB1" headercolor="#666" databg="#FAF0D4, #F3DFA8" headerrows="2" footerrows="1" }%

Table with two Header Rows and Footer Row
Num	Status	Action	Who	When	Progress
Num	Status	Action	Who	When	Progress
1	C	Chose new colours	John	1-Dec-02
2	X	Release	John	1-Apr-02
3		Get feedback	Anne	1-Feb-02
12	C	Spec error handling	Jack	1-Dec-02
5		Abc	John

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 with supported date formats View date formatsView date formats
  • Default Foswiki format
    • 31 Dec 2001 - 23:59
    • 31-Dec-2001 - 23:59
  • Foswiki format without time (defaults to 00:00)
    • 31 Dec 2001
    • 31-Dec-2001
  • Date separated by '/', '.' or '-', time with '.' or ':'
  • Date and time separated by ' ', '.' and/or '-'
    • 2001/12/31 23:59:59
    • 2001.12.31.23.59.59
    • 2001/12/31 23:59
    • 2001.12.31.23.59
    • 2001-12-31 23:59
    • 2001-12-31 - 23:59
    • 2009-1-12
    • 2009-1
    • 2009
  • ISO format
    • 2001-12-31T23:59:59
    • 2001-12-31T
  • ISO dates may have a timezone specifier, either Z or a signed difference in hh:mm format. For example:
    • 2001-12-31T23:59:59+01:00
    • 2001-12-31T23:59Z
• Number is digits, with optional decimal point
• Otherwise treated as text

If you specify headerrows, then the row with the sort links is the row closest to the data (the last row in the header). If you do not specify headerrows, the first row that has a heading in the first column is the sort row. To sort by the first footer row, set headerrows="0".

Sorting example

Number	Decimal	Alpha	Date
1	9.9	vwx	01 Jan 1990
2	9.91	stu	31 Dec 1999
3	9.09	pqr	15 Jan 2006

Row spans

Table cells with a single caret indicate follow-up rows of multi-row spans. For example,

| One One | One Two | One Three |
| ^ | Two Two | Two Three |
| Three One | ^ | Three Three |

Results in:

One One	One Two	One Three
	Two Two	Two Three
Three One		Three Three

Note: Row spans do not work across the header and body boundaries of a table. So it you have a header row, the row cells beneath (in the body section) cannot be merged with the header row cells. Row spans within header cells are possible.

%TABLE{headerrows="2" sort="off"}%
| *One One* | *One Two* | *One Three* |
| ^ | *Two Two* | *Two Three* |
| Two One | Two Two | Two Three |
| Three One | ^ | Three Three |

Results in:

One One	One Two	One Three
	Two Two	Two Three
Two One	Two Two	Two Three
Three One		Three Three

Col spans

Col spans can be achieved by writing table cell separators without contents or spacing:

%TABLE{tablerules="cols"}%
| *Mammals* ||
| Monotremes | Echidna, Platypus |
| Marsupials | Kangaroo, Koala |
| Placentals ||
| Fish (to write) ||

Results in:

Mammals
Monotremes	Echidna, Platypus
Marsupials	Kangaroo, Koala
Placentals
Fish (to write)

TablePlugin Global Settings

You can override the default settings for the plugin by defining the following preferences.

Preference	Meaning	Default
TABLEPLUGIN_SORT	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.	all
TABLEPLUGIN_TABLEATTRIBUTES	Default table attributes. These are first defined in Configure, and can be set on site level in Main.SitePreferences, on web level in WebPreferences or on topic level.	tableborder="1" valign="top" headercolor="#000000" headerbg="#d6d3cf" headerbgsorted="#c4c1ba" databg="#ffffff,#edf4f9" databgsorted="#f1f7fc,#ddebf6" tablerules="rows" headerrules="cols"

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

.foswikiTable	The table
.foswikiSortedCol	A sorted column
.foswikiSortedAscendingCol	Sorted column, ascending
.foswikiSortedDescendingCol	Sorted column, descending
.tableSortIcon	The sort icon holder (span)
.foswikiFirstCol	The first column
.foswikiTableEven	Even numbered rows
.foswikiTableOdd	Odd numbered rows
.foswikiTableCol + column number	Unique column identifier, for instance: foswikiTableCol0
.foswikiTableRow + type + row number	Unique row identifier, for instance: foswikiTableRowdataBg0

Images used by TablePlugin

Sort icons in the header are read from DocumentGraphics.

	Sort ascending
	Sort descending
	Generic sort button if header label is a link, not a sort link

Plugin Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

16 Sep 2009	1.110: Arthur Clemens: Added attributes headerrules and datarules. Fixed potential bug where Explorer won't render more than 20 table CSS tags. Fix sorting on IP addresses.
13 Sep 2009	1.100: Arthur Clemens: Removed HTML formatting in favor of a pure CSS rendering. Code refactoring and bug fixes: • Fixed a bug that ignored cellspacing (Foswikitask:Item8270). • Sorting is now possible with multiple header rows (Foswikitask:Item8122). • Fixed sorting of dates prior to 1970.

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.

23 Jun 2007	1.022: Arthur Clemens: Fixed styling of param tablerules on Internet Explorer.
23 May 2007	1.021: Michael Daum: Fixed css attribute priority to cooperate nicely with skin themes.
27 Dec 2006	1.020: Kenneth Lavrsen: Fixed initsort so all tables can be initsorted and not only the first. When you sort a table by clicking on the header of a column the table gets sorted accordingly. When you click the header of another table the previously sorted table goes back being sorted as specified by initsort.
13 Dec 2006	1.019: Arthur Clemens: Prevent sorting of columns that do no exist.
02 Dec 2006	1.018: Arthur Clemens: Data rows now start with first datacolor and databgcolor.
