## Crosstabs

A crosstab summarizes data and presents the summaries in a compact row and column format. In JReport, crosstabs are data containers, which means that when a crosstab is inserted into another data container, you can set up data container link between the crosstab and its parent according to your requirements (for details, see the section Setting up data container link).

Meanwhile, in order to meet the requirements from voice agents used by people with eyesight disabilities, JReport supports exported crosstab components in the HTML data table format to get a section 508 compliant result. For detailed descriptions, refer to Accessibility.

Pick a task from the following:

- Inserting a crosstab
- Modifying a crosstab
- Defining comparison functions in a crosstab
- Expanding/Collapsing a crosstab

See an example: The SampleComponents catalog, included with JReport Designer, contains reports that have examples of how each component type could be used in a report. For the crosstab component example, open `<install_root>\Demo\Reports\SampleComponents\Crosstab.cls`.
