You can apply some filters to a table so as to reduce the records displayed in the table.
To add filter conditions to a table:
To make some conditions grouped, select them and click the Group button, then the selected conditions will be added in one group and work as one line of filter expression. Conditions and groups together can be further grouped. To take any condition or group in a group out, select it and click Ungroup.
To adjust the priority of the conditions, select it and click the Up or Down button.
To delete a condition line, select it and click the Delete button.
Then when you preview the table, only data satisfying the specified filter conditions are shown.
