Define the table rows and columns using the STYLE_PRECEDENCE option. The TABLE statement creates a table per product per page, A100. The TABLE statement also creates a row for each formatted value of Region and creates a column for each formatted value of SaleType. Each cell that is created by these rows and columns contains the sum of the analysis variable Net Sales for all observations that contribute to that cell. The STYLE= option in the dimension expression overrides any other STYLE= specifications in PROC TABULATE that specify attributes for the table cells. In this second table, the STYLE_PRECEDENCE option is specfied on the page expression. Therefore, the style that applies to the background is yellow.

table product *{style={background=red}},
region*{style={background=yellow}},
saletype*{style={background=orange}} / style_precedence=page;
