Interface for simple column decorators.

A column decorator is called after the object has been retrieved and it can "transform" the object before the rendering.

The DisplaytagColumnDecorator interface has been introduced in displaytag 1.1 and replaces the previous ColumnDecorator interface, adding the pageContext and media parameters, and changing the return type to object to allow decorator chaining.
