Table Plugin

Introduction

The TablePlugin gives extra control of TWiki table rendering using | cell 1 | cell 2 | syntax:

• Sort table by columns
• Use TML (TWiki Markup Language) in table cells using |>> TML <<| syntax.
• Support row spans using |^| syntax.
• Change table properties, such as border width, cell spacing and cell padding.
• Change background color and text color for header cells.
• Change background color and text color for data cells - colors can alternate.
• Set and override table attributes in this order:
  • Default TABLEATTRIBUTES Plugin setting in current topic.
  • A TABLEATTRIBUTES preferences setting on site-level (TWikiPreferences) or web-level (any WebPreferences), such as:
    • Set TABLEATTRIBUTES = tableborder="0" cellpadding="1" ...
  • Before a table using %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 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

Using TML in table cells

A TWiki table has a line-oriented markup, e.g. normally it is not possible to use other line-oriented TML, such as bullets or nested tables.

It is possible to introduce newlines in a table cell if the cell is enclosed in double-angle brackets, such as |>> TML <<|. Example:

| *A1* | *B1* | *C1* | *D1* |
| A2 |>> B2
   * Bullet
   * list
   * is
   * possible
<<|>> C2
  | *C2.1* | *C2.2* |
  | Embedded | table |
  | possible | too |
end C2
<<| D2 |
| A3 | B3 | C3 | D3 |

Row spans

Table cells with a single caret indicate follow-up rows of multi-row spans. Example:

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

Table Attributes

Attributes are defined as a TABLEATTRIBUTES Plugin setting in this topic, a TABLEATTRIBUTES preferences setting, or on line before the table using %TABLE{...}%:

• Supported attributes:

  Argument	Comment	Default value	Example
  valign	Vertical alignment of cells and headers, set to "top", "middle", "bottom" or "baseline".	unspecified	valign="top"
  tablewidth	Table width: Percentage of window width, or absolute pixel value.	unspecified	tablewidth="100%"
  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).	unspecified	tablerules="rows"
  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).	unspecified	tableframe="hsides"
  tableborder	Table border width (pixels).	"1"	tableborder="2"
  summary	Table summary used by screenreaders: A summary of what the table presents. It should provide an orientation for someone who listens to the table.	unspecified	summary="List of subscribed users"
  sort	Set table sorting by clicking headers "on" or "off".	unspecified	sort="on"
  initsort	Column to sort initially ("1" to number of columns).	unspecified	initsort="2"
  initdirection	Initial sorting direction for initsort, set to "up" (descending) or "down" (ascending).	unspecified	initdirection="up"
  id	Unique table identifier string, used for targeting a table with CSS.	tableN (where N is the table order number on the page)	id="userTable"
  headervalign	Vertical alignment of header cells; overrides valign.	unspecified	headervalign="top"
  headerrows	Number of header rows to exclude from sort. (will be rendered in a HTML thead section)	(determined automatically)	headerrows="2"
  headercolor	Header cell text color.	"#ffffff"	headercolor="#0000cc"
  headerbgsorted	Header cell background color of a sorted column.	the value of headerbg	headerbgsorted="#32596c"
  headerbg	Header cell background color.	"#6b7f93"	headerbg="#999999"
  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.	unspecified	headeralign="left,right"
  footerrows	Number of footer rows to exclude from sort. (will be rendered in a HTML tfoot section)	"0"	footerrows="1"
  disableallsort	Disable all sorting, both initsort and header sort. This is mainly used by plugins such as the EditTablePlugin to disable sorting in a table while editing the table.	unspecified	disableallsort="on"
  datavalign	Vertical alignment of data cells; overrides valign.	unspecified	datavalign="top"
  datacolor	Data cell text color, a comma separated list.	unspecified	datacolor="#0000CC, #000000"
  databgsorted	Data cell background color of a sorted column; see databg.	the values of databg	databgsorted="#d4e8e4,#e5f5ea"
  databg	Data cell background color, a comma separated list. Specify "none" for no color, that is to use the color/background of the page the table is on.	"#edf4f9,#ffffff"	databg="#f2f2f2,#ffffff"
  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.	unspecified	dataalign="center"
  columnwidths	Column widths: Comma delimited list of column widths, percentage or absolute pixel value.	unspecified	columnwidths="80%,20%"
  cellspacing	Cell spacing (pixels).	"0"	cellspacing="3"
  cellpadding	Cell padding (pixels).	"0"	cellpadding="0"
  cellborder	Cell border width (pixels).	unspecified	cellborder="0"
  caption	Table caption: A title that will be displayed just above the table.	unspecified	caption="Users"

The %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 %TABLE{...}%

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

Table with 4 digit year dates and no use of %TABLE{...}%

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

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.

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.
