Comment 1 for bug 61735

We only allow column-click-sorting of tables on pages that don't have batching. It is so because the sorting is done with javascript and thus we can sort only the current batch.

We could make the column headers be links and thus do the sort on the server, but that would require an extra page load and wouldn't be trivial because some columns contain computed values from multiple database columns.

I, myself, like the javascript sorting even for tables on pages with batching, because I know that it will sort only the current batch and thus I know what to expect. But I know this may be confusing for some users, and this is why it was disabled on such pages.
