In a PivotTable, users can collapse different fields. For example:
Group order dates by year and month, or group test scores in bands of 10.
Users can collapse any field in the rows/columns, which gives a quick view of the statistics.
Users can expand or collapse a specific item in a pivot field, and see only its heading. The other items in that field will not be affected.
