    Row labels are used to apply a filter to one or more rows that have to be shown in the pivot table. For instance, if the "Salesperson" field is dragged on this area then the other output table constructed will have values from the column "Salesperson", i.e., one will have a number of rows equal to the number of "Sales Person".

A label is a string containing the distance information between the current node (the node of the row) and all the other nodes that can be reached with an ascending search on the relative multi-level structure. The advantage of these distances is that they all represent the shortest paths.
