14 * Uses 'tableSorterCollation' in mw.config (if available)

16 * Create a sortable table with multi-column sorting capabilities

21 * // Create a tablesorter interface, initially sorting on the first and second column
22 * $( 'table' ).tablesorter( { sortList: [ { 0: 'desc' }, { 1: 'asc' } ] } );
23 *
24 * @param {string} [cssHeader="header"] A string of the class name to be appended to sortable
25 * tr elements in the thead of the table.
26 *
27 * @param {string} [cssAsc="headerSortUp"] A string of the class name to be appended to
28 * sortable tr elements in the thead on a ascending sort.
29 *
30 * @param {string} [cssDesc="headerSortDown"] A string of the class name to be appended to
31 * sortable tr elements in the thead on a descending sort.
32 *
33 * @param {string} [sortMultisortKey="shiftKey"] A string of the multi-column sort key.
34 *
35 * @param {boolean} [cancelSelection=true] Boolean flag indicating iftablesorter should cancel
36 * selection of the table headers text.
37 *
38 * @param {Array} [sortList] An array containing objects specifying sorting. By passing more
39 * than one object, multi-sorting will be applied. Object structure:
40 * { <Integer column index>: <String 'asc' or 'desc'> }
41 *
42 * @event sortEnd.tablesorter: Triggered as soon as any sorting has been applied.
