The "footer = no" parameter can be used to specify that the no footer is included in the table. When the templates parameter (for rendering cells in the table) is provided, "footer = no" seems to be ignored. For instance:
<!-- renders a table without a footer -->
{{#sparql:select ?s { values ?s { <http://example.org/> } }|footer = no}}
<!-- renders a table with a footer -->
{{#sparql:select ?s { values ?s { <http://example.org/> } }|footer = no|templates=show}}
