Using sortable tables
When browsing Wikipedia you may encounter tables that have been made sortable. A sortable table is identified by the arrows in one or more of its header cells. Clicking them will cause the table rows to sort in ascending order based on the selected column. A second click on the same arrow will sort in descending order. A third click will restore the original order of the whole table. For example; a third click causes List of countries by intentional homicide rate to reset to its original order by subregion.
The actual sorting process will happen on your computer using client-side JavaScript. For this reason it is only possible to use this functionality if you have JavaScript enabled in your web browser. The sorting process is also dependent on your computer and the amount of data. Sorting a very large table on a slow computer may take a long time.

Tables with complex headers
Tables with more complex headers than before now sort correctly. For example:
