[[Help:Table|Tables]] can be made sortable via [[client-side JavaScript|client-side JavaScript]] with <code>class="sortable"</code>. Sortable tables are identified by the arrows in each of its header cells. Clicking them will cause the table rows to sort based on the selected column, in ascending order first, and subsequently toggling between ascending and descending order. Links and other wiki-markup are not possible in headers.

This works in MediaWiki 1.9, which is installed in all Wikimedia projects. Sortable tables are identified by the arrows in each of its header cells.

==Sort modes==
The sort modes (the [[w:data type|data type]]s, which, in addition to the choice "ascending" or "descending", determine the sorting order) are as follows; in the given order (as soon as there is a match, subsequent criteria are not applicable, e.g., 24-12-2007 is a date, not a number. For the criteria, tags (e.g. span, sup, sub) are ignored.

**criterion: the first non-blank element is of the form "dd-dd-dddd", "dd-dd-dd", or "dd aaa dddd"; or, in the last case, text follows ending with "sm=d" (without the quotes; it stands for "sort mode = date"). (In hidden form this can conveniently be done with {{tim|smd}}.)

Text after a number (e.g. a footnote) does not affect the sorting order, if the sorting ''mode'' is numeric. However, if the number at the top has text after it, this makes the sorting mode alphabetic, unless it ends with a (typically invisible) "sm=n".

If at some point (i.e., after possible previous sorting) the form <code><nowiki>[[YYYY]]</nowiki></code> is at the top with a non-negative year, sorting would be numerical; in this case, after toggling between ascending and descending there would be no proper sorting ''within'' each year (because [http://www.devguru.com/technologies/ecmascript/QuickRef/parsefloat.html parsefloat] is applied, finding the first number in the string, and basing sorting on only that number). Also, years BC would not be sorted properly. Therefore, alphabetic sorting has to be enforced. This can be done by putting a non-displayed character after the year, separated by a space.

The two-character entries such as A1 demonstrate that A and a are at the same position.
