Table.pivot(CategoricalColumn<?> column1,
CategoricalColumn<?> column2,
NumericColumn<?> column3,
AggregateFunction<?,?> aggregateFunction)
Returns a pivot on this table, where: The first column contains unique values from the index
column1 There are n additional columns, one for each unique value in column2 The values in each
of the cells in these new columns are the result of applying the given AggregateFunction to the
data in column3, grouped by the values of column1 and column2
