  Component Parameters
  Name | Type | Flags | Default | Default Prefix
  --- | --- | --- | --- | ---
  gridModel | org.apache.tapestry5.grid.GridModel |  | componentResources.container | prop
  The object that provides access to bean and data models, which is typically the enclosing Grid component.
  index | int |  |  | prop
  Optional output parameter that stores the current column index.
  lean | boolean |  |  | prop
  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 | org.apache.tapestry5.PropertyOverrides |  | this | prop
  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.
  zone | String |  |  | prop
  If not null, then each link is output as a link to update the specified zone.
