Sortable results columns (ways to sort results)

[prototyperspective]

Could you please make it possible to sort the results?

For example when showing results for some category intersections of files on Wikimedia Commons I'd like to sort them by file-name or file-type (such as video or at least webm).

The columns are not clickable to sort the results. (Further ways to sort other than the displayed columns would be useful too.)
