You can use Interactive Viewer to improve the presentation of data in a cross tab. You can modify the appearance of the dimensions and measures in a cross tab by specifying formatting properties. For example, to indicate that the numbers displayed in the cross tab are currency amounts, you apply the currency format that displays a currency symbol alongside the amount. It is also easier to read the numbers if they are aligned to the right. Using color, you can differentiate the product line subtotals that run horizontally across the report, from the quarterly and yearly grand totals that run vertically down the report.
