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