Component Parameters
Name	Type	Default	Default Prefix

gridModel	The object that provides access to bean and data models, which is typically the enclosing Grid component.
index	int		prop
index	Optional output parameter that stores the current column index.
lean	boolean		prop
lean	If true, then the CSS class on each <TH> element will be omitted, which can reduce the amount of output from the component overall by a considerable amount. Leave this as false, the default, when you are leveraging the CSS to customize the look and feel of particular columns.

overrides	Where to look for informal parameter Blocks used to override column headers. The default is to look for such overrides in the GridColumns component itself, but this is usually overridden.
