‎<presort>

The Presort extension adds a <presort> tag to the wiki markup. This tag can be used around sortable and non-sortable wikitables to presort the table without the need of an ordered wikitext.

ParameterEdit

modeEdit

  • column

The table is presorted according to the values in a column.

  • key

The table is presorted according to a key.
Default value is "column".

sortcolumnEdit

defines the sortcolumn. Can only be used with "column" mode. Numbering starts with 1.
Default value is "1".

orderEdit

  • asc

ascending order

  • desc

descending order
Default value is "asc".

numberingcolumnEdit

Allows to define a columnnumber, in which automated numbering is filled in. All existing content in this column is overwritten! Default value is -1, which means no numbering.

templateEdit

Allows to define the template used for the key definition. For example templates like dts, sort or hiddensort. Can only be used with "key" mode.
Default value is "dts".

InstallationEdit

  • Download and place the file(s) in a directory called Presort in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    require_once "$IP/extensions/Presort/Presort.php";
    
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
