You can customize page layout using StyleSheet attributes. The page layout attributes available to you, like all other attributes, depend on the display format. For instance, some attributes support print-oriented display formats such as PDF, and they do not apply to HTML reports displayed in a browser. For details on display formats, see Choosing a Display Format and Saving and Reusing Your Report Output.
A report page has default layout characteristics. However, you can change any of them to customize the layout. You control a report's appearance, including column arrangement on a page, page numbering, page breaks, use of grids and images, and much more.
You can use SET parameters in place of most StyleSheet attributes to define page layout characteristics. For details on SET, see the Developing Reporting Applications manual.
