Makes headers of HtmlTable clickable to sort the rows.

• HtmlTable

new HtmlTable([table, options]);

1. table - (mixed; optional) - a Table DOM element or it's id; if you do not specify one, one will be created.
2. options - (object; optional) a key/value set of options.

• all options defined by HtmlTable, plus:
• sortIndex - (integer) the row to sort on startup; defaults to 0. Set to null if you don't want to sort on startup.
• sortReverse - (boolean) if true, the initial sorted row will be sorted in reverse. Defaults to false.
• parsers - (array) a mapping of parsers for each column of data. See section on parsers below.
• defaultParser - (string) if no parsers are defined and they cannot be auto detected, which parser to use; defaults to 'string'
• classSortable - (string) the class to add to the table when sorting is enabled; defaults to 'table-sortable'
• classHeadSort - (string) the class to add to the th that has the current sort (applied when sort order is forward); defaults to 'table-th-sort'
• classHeadSortRev - (string) the class to add to the th that has the current sort (applied when sort order is reverse); defaults to 'table-th-sort-rev',
• classNoSort - (string) if a th has this class, it will not be sortable; defaults to 'table-th-nosort'
• classGroup - (string) class applied to td elements when more than one has the same value; defaults to 'table-tr-group',
• classGroupHead - (string) class applied to the first td in a group of td elements that have the same value; defaults to 'table-tr-group-head'
• classCellSort - (string) the class applied to td elements that are in the current sorted column. defaults to 'table-td-sort'
• classSortSpan - (string) the class applied to a span element injected into the th headers when sorting is enabled; useful for adding an arrow background for the sorted column to indicate the sort direction. defaults to 'table-th-sort-span'
• sortable - (boolean) enables the sortable feature on invocation. Defaults to false.

• onSort - callback executed when a column is sorted; passed the tbody and the index of the column sorted.

Your Table must have a thead with th elements for each column (these are what the user clicks on to sort stuff). If your table doesn't have headers already, you can specify them with the headers option or use the setHeaders method.

Sorts a column.

myHtmlTable.sort(index, reverse, prepare);

1. index - (integer) the index of the column to sort
2. reverse - (boolean) reverses the sort if true; defaults to false
3. prepare - (boolean) if the sort has a secondary sort, set this value to true on the first sort, and false on the second. For example, if you sorted a directory list of files first by type and then secondly by file size, you would sort on type and pass true and then sort on size and pass false.

• (object) This instance of HtmlTable.

Enables the sortable features of the table.

myTable.enableSort();

• (object) This instance of HtmlTable.

Disables the sortable features of the table.

myTable.disableSort();

• (object) This instance of HtmlTable.

Reapplies the current sort. Note that this is called whenever new rows are added.

myTable.reSort();

• (object) This instance of HtmlTable.

There are numerous parsers used by HtmlTable to determine the sort order of data. A column of numbers, for example, will be sorted numerically, while a column of dates will be sorted by their date order. The HtmlTable.Parsers hash contains a group of objects each with a regular expression and a function applied when that expression matches the content. For example, here is the parser for number:

HtmlTable.Parsers.number = {
    match: /^\d+[^\d.,]*$/,
    convert: function() {
        return this.get('text').toInt();
    },
    number: true
};

You'll note that there's also a number value. Numerical parsers should have this flag for proper sorting. Also note that "this" is bound to the table cell.

• date - sorts for date formats that are matched by Date.parse
• input-checked - sorts checkbox inputs into those that are checked and are not checked
• input-value - sorts based on the value inside text inputs
• number - sorts on integers
• numberLax - sorts on integer values that might be mixed with other data.
• float - sorts on float values
• floatLax - sorts on float values that might contain other data.
• string - an alpha sort
• title - sorts on the title property of the table data element

Because these parsers in the list above are run in order, adding a custom parser is likely to produce no results, as your table contents will eventually match one of the items above. Therefore there is a static method for adding your own parsers that will put your parser at the top of this list. Example:

HtmlTable.defineParsers({
    foo: {
        match: /foo/,
        convert: function(){...},
        number: false
    }
});
