The Row Header determines the label for the rows in a table. The Field name defines which field from the list to use for the row names. This section allows for sorting the rows in ascending (Asc) or descending (Desc) order. Check off Show Totals Row to show the total of all values in the given column. The Allow Drilldown checkbox allows for clicking any of the row names to bring up a filtered list view of the items matching that row name.
