'Returns the canonical URL for this table.
This is used for the POST action attribute on the form element
wrapping the table. In many cases it is also useful for redirecting
after a successful action on the table.
For convenience it defaults to the value of
``request.get_full_path()`` with any query string stripped off,
e.g. the path at which the table was requested.'
