By utilizing the aggregation and grouping features, you can establish groups within the Result Matrix and subsequently perform aggregation operations on these groups, such as SUM, COUNT, etc.

.withRows(rows)
// Property `.withGroupBy` defines that the `TextColumn1` and `NumericColumn3` are used for group by (The order is important).
.withGroupBy(['TextColumn1', 'NumericColumn3'])
// Property `.withColumnAggregation` defines the values for subtotal rows that will be calculated as SUM.
// Values are based on the group by definition (`NumericColumn3`). This definition is optional.
// When not used, like e.g. for `TextColumn1`, there will be no aggregation calculated for the `TextColumn1`.
.withColumnAggregation('NumericColumn3', SUM)
// Property `.calculateGroupByData` is an end statement for group definition.
// This statement is only used together with `.withColumnAggregation`.
