~~DPL~~ allows you to define the sort order of its output as is explained below.

DPL3 allows you to define the sort order of its output as is explained below.

In some cases this is not sufficient, however. Think of the following example: You create a list of pages which use a certain template. You want to show the value of the first parameter each page uses when calling that template. This can easily be done with the [[include]] feature of DPL. If you now wanted the output to be sorted by the value of that parameter DPL could not help because it had to ~~analyse~~ all articles before finding those parameter values.

But there is another way: Create a ''sortable wiki table'' (using the [[table]] option of DPL with 'class=sortable') and you can click on the column headings to sort your output accordingly. However, the initial order shown in that table will still be the order in which DPL parsed the wiki pages (usually an alphabetic order of the page names).
