The outliner displays tabular text data. It is a simpler version of the tree but can handle larger numbers of rows more efficiently. The outliner should contain one or more outlinercol elements, and one outlinerbody elements. You can also place splitter elements between the columns to allow column resizing.

The outliner content is calculated via a script object which you supply and assign to the outliner. This object should contain functions which calculate cell data. The content may also be generated via an RDF datasource with a template, in which case one can also use the outlinerrow and outlinercell elements.
