How this page is built
the gem renders it — this is all you write
A full table — search, an inline filter row, sortable columns and row actions — all derived from the model. This page toggles between the curated :index and the fuller :catalog fieldset (currently :index). Your controller assigns @books — scope it for authorization (e.g. Book.accessible_by(current_ability)) and the gem renders that scope.
