No. There is no way to make element "versions" displayed as a table
collapsible.
Element "versions" displayed as a table is a ``pure table'', that is a
group of rows. And a ``pure table'' (just like table-row-groups) is not
collapsible.
The situation is different for DocBook and XHTML tables which are not
``pure tables''. They can contain "caption" or "title" elements for
example. This makes DocBook and XHTML tables very close to plain blocks
(which are collapsible).
I'm sorry if this explanation is obscure.
