Adding filters to tables in Report Designer

Hi all. I wanted to be able to filter data in a table report item within a master-detail report. I have done this using a master table containing an ID, and then in the repeating rows (with page breaks) I have successfully put charts with the data filtered on that ID. However I cannot find where the option to filter data in what is essentially a nested table. Any help would be appreciated. I am on KNIME 3.4.1. 

Ah, I found it. In BIRT under the "Filters" tab for the table property sheet when I highlight that. :-)
