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