16 * @description Create a sortable table with multi-column sorting capabilitys
18 * @example $('table').tablesorter();
19 * @desc Create a simple tablesorter interface.
21 * @example $('table').tablesorter({ sortList:[[0,0],[1,0]] });
22 * @desc Create a tablesorter interface and sort on the first and secound column column headers.
24 * @example $('table').tablesorter({ headers: { 0: { sorter: false}, 1: {sorter: false} } });
26 * @desc Create a tablesorter interface and disableing the first and second column headers.
29 * @example $('table').tablesorter({ headers: { 0: {sorter:"integer"}, 1: {sorter:"currency"} } });
31 * @desc Create a tablesorter interface and set a column parser for the first
36 * settings An object literal containing key/value pairs to provide
40 * @option String cssHeader (optional) A string of the class name to be appended
41 * to sortable tr elements in the thead of the table. Default value:
44 * @option String cssAsc (optional) A string of the class name to be appended to
45 * sortable tr elements in the thead on a ascending sort. Default value:
48 * @option String cssDesc (optional) A string of the class name to be appended
49 * to sortable tr elements in the thead on a descending sort. Default
50 * value: "headerSortDown"
52 * @option String sortInitialOrder (optional) A string of the inital sorting
53 * order can be asc or desc. Default value: "asc"
55 * @option String sortMultisortKey (optional) A string of the multi-column sort
56 * key. Default value: "shiftKey"
58 * @option String textExtraction (optional) A string of the text-extraction
59 * method to use. For complex html structures inside td cell set this
60 * option to "complex", on large tables the complex option can be slow.
61 * Default value: "simple"
63 * @option Object headers (optional) An array containing the forces sorting
64 * rules. This option let's you specify a default sorting rule. Default
67 * @option Array sortList (optional) An array containing the forces sorting
68 * rules. This option let's you specify a default sorting rule. Default
71 * @option Array sortForce (optional) An array containing forced sorting rules.
72 * This option let's you specify a default sorting rule, which is
73 * prepended to user-selected rules. Default value: null
75 * @option Boolean sortLocaleCompare (optional) Boolean flag indicating whatever
76 * to use String.localeCampare method or not. Default set to true.
79 * @option Array sortAppend (optional) An array containing forced sorting rules.
80 * This option let's you specify a default sorting rule, which is
81 * appended to user-selected rules. Default value: null
83 * @option Boolean widthFixed (optional) Boolean flag indicating if tablesorter
84 * should apply fixed widths to the table columns. This is usefull when
85 * using the pager companion plugin. This options requires the dimension
86 * jquery plugin. Default value: false
88 * @option Boolean cancelSelection (optional) Boolean flag indicating if
89 * tablesorter should cancel selection of the table headers text.
92 * @option Boolean debug (optional) Boolean flag indicating if tablesorter
93 * should display debuging information usefull for development.
