Description

Thanks for creating this great library 👍 !

I follow this documentation to create a pivot table.

Is it possible to make an horizontal grouping like in this example (add gender to rows) ?

pivot { col1 then col2 } .groupBy { row1 and row2 } col1 and c2 are grouped hierarchically but row1 and row2 are not.
