Flat table aggregation

[Q&A Bot]

Q: 
I’m exploring Seektable and would like to know if there is a way to aggregate data when using flat table output.

Flat-table displays rows as they are returned by "Select Query" that is specified in the SQL-based cube configuration. 

You can specify GROUP BY here to provide already pre-aggregated data to SeekTable -- or, as an alternative, use a pivot table with dimensions that are selected only on "Rows" + hide "Totals" column.
