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

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.
