Reports can be divided into section or groups. By picking a field as a group by, the report will effectively stop and start again each time the value of the field changes.
You can add a section footer at the bottom of each column that either sums up the numeric information in the column or counts the number of text entries in section.
You can add multiple Group by widgets. If you select fields like Region, Supervisor and Employee as Group by' ;s, the report will break each time there is a new region, new supervisor within a region or a new employee under that supervisor.
