You need to define a data source to output data to your table component. The reporting tool must know how many times the cells in the table should be printed. Therefore, the table component should have a reference to the data source. There are several ways to do this. Use a table editor. Double-clicking the table header calls the editor. You can also use the table's DataSource property to invoke the table editor.

The Table editor allows selecting data sources.

Data sources can be selected by clicking the first tab of the editor. All data sources are grouped into categories. Each category corresponds to one connection with data in the report data dictionary. The figure below shows the table editor.
