Attachment macro is a sortable table

The attachments macro display all attachments in a sortable table. That mean that if you click on a header, the table will be sorted alphabetically by this column. This behaviour clashes with the one when you click on the word on the header, which sort the content by that column (not alphabetical order but order by date, size,...).

These two different behaviours for clicking in the same thing are confusing fro end users.
