+=item C<sortable_table_header $by, %params>
+
+Create a link and image suitable for placement in a table
+header. C<$by> must be an index set up by the controller with
+L<SL::Controller::Helper::make_sorted>.
+
+The optional parameter C<$params{title}> can override the column title
+displayed to the user. Otherwise the column title from the
+controller's sort spec is used.
+
+The other parameters in C<%params> are passed unmodified to the
+underlying call to L<SL::Controller::Base::url_for>.
+
+See the documentation of L<SL::Controller::Helper::Sorted> for an
+overview and further usage instructions.
