Having Created a Connection, selected your database connection and defined a SELECT action.
Using the Connect behaviour on the appropriate event (possibly the When Forms is Opened event), select the database connection and action, and then in the Return Parameters section, chose the return parameter (field) you want to populate your table column with and click on Target: select the table object and expand to see its columns; If you want the column to be populated with data from a database column, select Table Column - All rows, this will add the corresponding rows to the table and populate them with the selected data.
