A Row Label (in a Pivot Table) determines a table column that is used to group individual table rows (i.e. records) by the unique values in that specific column. It is called a Row Label as the unique values are listed at the beginning of each row (in the first column) of the resulting Pivot Table. For example, selecting a Sales Person Name as a Row Label will list all Sales Persons in the first column and next we can group their total sales.
