TablePlugin < System < BACCHUS Wiki

---+ 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= [[%SYSTEMWEB%.PreferenceSettings][preference]], or on the line before the table using =%<nop>TABLE{...}%=:
%INCLUDE{"%SYSTEMWEB%.VarTABLE" section="table_attributes"}%

---+++ Specifying and overriding attributes
Table attributes can be set in different ways. In top down order:
   1 As default preference in [[%SCRIPTURL{"configure"}%/#TablePlugin$Extensions][Configure]].
   1 As preference in a topic: =TABLEPLUGIN_TABLEATTRIBUTES=: =Set TABLEPLUGIN_TABLEATTRIBUTES = tableborder="0" cellpadding="1" ...=
   1 As parameters to the =TABLE= macro: =%<nop>TABLE{ tableborder="0" cellpadding="4" cellspacing="3" cellborder="0" }%=

The preference =TABLEPLUGIN_TABLEATTRIBUTES = ...= competely overrides previous preferences (for example in <nop>%MAINWEB%.SitePreferences or Configure):
<pre class="tml">
   * <nop>Set TABLEPLUGIN_TABLEATTRIBUTES = cellpadding="0" <span class="foswikiGrayText">&lt;&lt;&lt; this will remove previously set preferences and leave only 1 attribute</span>
</pre>
If you pass =%<nop>TABLE{...}%= parameters, you partially override previously set preferences:
<pre class="tml">
   * %<nop>TABLE{datacolor="#f00"}% <span class="foswikiGrayText">&lt;&lt;&lt; this will only change the data color attribute</span>
</pre>

---+++ 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 %<nop>TABLE{...}%

Line before table: <pre class="tml">%<nop>TABLE{ sort="on" tableborder="0" cellpadding="4" cellspacing="3" cellborder="0" headerbg="#D5CCB1" headercolor="#666" databg="#FAF0D4, #F3DFA8" headerrows="2" footerrows="1" }%</pre>

%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* |
| 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 | | |
| *Num* | *Status* | *Action* | *Who* | *When* | *Progress* |

---+++ 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 %TWISTY{mode="span" link="View date formats" remember="on"}%
      * 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 %ENDTWISTY%
   * 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
%TABLE{databg="#ffffcc" databgsorted="#ffcc33" headercolor="#ffffff" headerbg="#990033" headerbgsorted="#660000" initsort="1"}%
| *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,

<verbatim class="tml">
| One One | One Two | One Three |
| ^ | Two Two | Two Three |
| Three One | ^ | Three Three |
</verbatim>

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.

<verbatim class="tml">
%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 |
</verbatim>

Results in:
%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 |

---+++ Col spans
Col spans can be achieved by writing table cell separators without contents or spacing:
<verbatim class="tml">
%TABLE{tablerules="cols"}%
| *Mammals* ||
| Monotremes | Echidna, Platypus |
| Marsupials | Kangaroo, Koala |
| Placentals ||
| Fish (to write) ||
</verbatim>

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

---++ <nop>%TOPIC% Global Settings

You can override the default settings for the plugin by defining the following [[%SYSTEMWEB%.PreferenceSettings][preferences]].

<!--
      * Set SHORTDESCRIPTION = Control attributes of tables and sorting of table columns
-->
| *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 [[%SCRIPTURL{"configure"}%/#TablePlugin$Extensions][Configure]], and can be set on site level in <nop>%MAINWEB%.SitePreferences, on web level in <nop>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"= |


---++ <nop>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 %SYSTEMWEB%.DocumentGraphics.
| <img src="%ICONURL{tablesortup}%" width="11" height="13" alt="Sort table ascending" border="0" />  | Sort ascending | 
| <img src="%ICONURL{tablesortdown}%" width="11" height="13" alt="Sort table descending" border="0" />  | Sort descending | 
| <img src="%ICONURL{tablesortdiamond}%" width="11" height="13" alt="Sort table" border="0" />  | 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".

If you have any problems, or if the extension isn't available in =configure=, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.

   * Test if the plugin is correctly installed:
      * Check above example if the table renders as expected
      * Try click on heading to sort.  Other tables should also be sortable

|  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=.  |
