While in the “UI Design” module, open the “Properties” panel on the right side.
After clicking on the main Table element, select the data connection from the “Data Sources” drop-down menu. (For example; customer list)
Click on the second Table element you added inside the main Table element and select a data connection from the “Data Sources” drop-down menu in the “Properties” panel. This data source should be another list inside the main Table element (for example, select the list of addresses in the customer list).
Finally, you can preview your application by clicking the “RUN” button in the upper right corner.
