Do you need to put more than one <display:table> in the same page, with independent pagination and sorting?

No problem: parameter in pagination, sorting and exporting are encoded to be processed only by the source table. The only requirement is to provide a different id attribute for the table. If you click on sorting or pagination links in one of the previous tables the other one doesn't get affected by that.
