You can visualize in your mind the virtual PivotTable Row fields and Column fields: The Row fields are Country, State/Region, and City. The Column fields are Color, Parent Category, and Category. We will refer to the letter N as the number of Row fields; in this case, N=3. We will refer to the letter M as the number of Column fields; in this case, M=3.
