For tables that use
relational data, you can add a column that shows a selected measure
as a percentage of a grand total. For relational crosstabulation tables,
you can show a selected measure as a percentage of a grand total,
a column total, a row total, or a subtotal. For multidimensional crosstabulation
tables, you can show a selected measure as a percentage of a grand
total, a column total, a row total, a column subtotal, or a row subtotal.
