EasyCatalog normally assigns one record to each row in a table. When populated, the table body rows will be altered to accommodate row per record. The Table->Filter… menu sets a table level option to only populates with records matching a certain criteria.

To remove the applied filter use the “Remove..” button. The filter is persisted with the table, so duplicating or using the table in templates is possible.
