Allows to discard empty list items or table rows (empty), items or table rows with no links (no-links), and items or table rows with links to empty index pages (no-items, anchors with CSS class projectdoc-no-docs) used by the Table Merger Macro. Also filtering is possible on full rows (full: every cell in a row has a non-empty value) or partially filled table rows (partial: at least on cell has an empty value).
