I have a report where I need to have rows that can consist of more than one line, e.g.:
column 1 column 2
Name a Position a
Institution a
Name b Position b
Instition b

The informations of column two come from one control element.

The detail section of the report can be expanded so that it can hold multiple lines. Just put the cursor on the bar at the bottom of it and drag down. Assuming that Name a, Position a, and Institution a all come from the same record they will be printed wherever their respective controls are positioned in the detail section.
