Sorting a Table (^) ❘ 439
Figure 19-2 shows how to sort by multiple columns. To do this, sort the fi rst column by clicking the
column header; then hold down the Shift key to click a second column header.

This example is primarily about setting up the proper HTML and then styling it with CSS. The
$.tablesorter() plugin’s default functionality provides the rest as soon as it is applied.
You can customize several aspects of $.tablesorter() using the options documented in Appendix T.
For example, you can change which keyboard key you have to press to select a second column for
sorting using the option sortMultiSortKey. The default value is 'shiftKey'; to make it the Option
(Mac) or Alt (Windows) key, you would change the value to 'altKey'.
