"""Display profile data as HTML.
TODO
====
- The javascript sorting code has a weird behavior. If you click on a column
to sort it, then click on a different column, the click on the previous
column, the sort order changes. I would prefer it it just went with the
previous sort order. However, fixing it is not obvious to me.
