17 * @description Create a sortable table with multi-column sorting capabilitys
18 *
19 * @example $( 'table' ).tablesorter();
20 * @desc Create a simple tablesorter interface.
21 *
22 * @example $( 'table' ).tablesorter( { sortList: [ { 0: 'desc' }, { 1: 'asc' } ] } );
23 * @desc Create a tablesorter interface initially sorting on the first and second column.
24 *
25 * @option String cssHeader ( optional ) A string of the class name to be appended
26 * to sortable tr elements in the thead of the table. Default value:
27 * "header"
28 *
29 * @option String cssAsc ( optional ) A string of the class name to be appended to
30 * sortable tr elements in the thead on a ascending sort. Default value:
31 * "headerSortUp"
32 *
33 * @option String cssDesc ( optional ) A string of the class name to be appended
34 * to sortable tr elements in the thead on a descending sort. Default
35 * value: "headerSortDown"
36 *
37 * @option String sortInitialOrder ( optional ) A string of the inital sorting
38 * order can be asc or desc. Default value: "asc"
39 *
40 * @option String sortMultisortKey ( optional ) A string of the multi-column sort
41 * key. Default value: "shiftKey"
42 *
43 * @option Boolean sortLocaleCompare ( optional ) Boolean flag indicating whatever
44 * to use String.localeCampare method or not. Set to false.
45 *
46 * @option Boolean cancelSelection ( optional ) Boolean flag indicating if
47 * tablesorter should cancel selection of the table headers text.
48 * Default value: true
49 *
50 * @option Array sortList ( optional ) An array containing objects specifying sorting.
51 * By passing more than one object, multi-sorting will be applied. Object structure:
52 * { <Integer column index>: <String 'asc' or 'desc'> }
53 * Default value: []
54 *
55 * @option Boolean debug ( optional ) Boolean flag indicating if tablesorter
56 * should display debuging information usefull for development.
57 *
58 * @event sortEnd.tablesorter: Triggered as soon as any sorting has been applied.
