About cross tabs
A cross tab displays summary or aggregate values, such as sums, counts, or averages, in a row‑and‑column matrix similar to a spreadsheet. For example, you can use a cross tab to view sales data for each product line, by year, or total sales for each product line, by geography, and so on.
You can export cross tab content to other formats such as Excel, Word, PowerPoint, PostScript, or PDF. You can also print cross tab content, modify charts, Flash charts and Flash gadgets in a cross tab, and save a cross tab as a BIRT design (.rptdesign) or BIRT document (.rptdocument) file.
