Table Plugin

Control attributes of tables and sorting of table columns


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{...}%.


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:

You write:
| *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 |
        You get:
A1 B1 C1 D1
A2 B2
  • Bullet
  • list
  • is
  • possible

C2.1 C2.2
Embedded table
possible too
end C2
A3 B3 C3 D3

Row spans

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

You write:
| One One | One Two | One Three |
| ^ | Two Two | Two Three |
| Three One | ^ | Three Three |
        You get:
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
    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"
    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"
    headerbg Header cell background color. "#6b7f93" headerbg="#999999"
    headerbgsorted Header cell background color of a sorted column. the value of headerbg headerbgsorted="#32596c"
    headercolor Header cell text color. "#ffffff" headercolor="#0000cc"
    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"
    databgsorted Data cell background color of a sorted column; see databg. the values of databg databgsorted="#d4e8e4,#e5f5ea"
    datacolor Data cell text color, a comma separated list. unspecified datacolor="#0000CC, #000000"
    tableborder Table border width (pixels). "1" 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). unspecified 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). unspecified tablerules="rows"
    cellpadding Cell padding (pixels). "0" cellpadding="0"
    cellspacing Cell spacing (pixels). "0" cellspacing="3"
    cellborder Cell border width (pixels). unspecified cellborder="0"
    valign Vertical alignment of cells and headers, set to "top", "middle", "bottom" or "baseline". unspecified valign="top"
    headervalign Vertical alignment of header cells; overrides valign. unspecified headervalign="top"
    datavalign Vertical alignment of data cells; overrides valign. unspecified datavalign="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. unspecified 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. unspecified dataalign="center"
    tablewidth Table width: Percentage of window width, or absolute pixel value. unspecified tablewidth="100%"
    columnwidths Column widths: Comma delimited list of column widths, percentage or absolute pixel value. unspecified columnwidths="80%,20%"
    headerrows Number of header rows to exclude from sort. (will be rendered in a HTML thead section) (determined automatically) headerrows="2"
    footerrows Number of footer rows to exclude from sort. (will be rendered in a HTML tfoot section) "0" footerrows="1"
    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"
    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"
    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.


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" }%

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

TablePlugin Global Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, for example, %TABLEPLUGIN_SHORTDESCRIPTION%

  • One line description, shown in the 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="all"

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.

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.
