| Name | Type | Flags | Default | Default Prefix | Description |
|---|---|---|---|---|---|
| gridModel | org.apache.tapestry.grid.GridModel | componentResources.container | prop | The object that provides access to bean and data models, which is typically the enclosing Grid component. | |
| 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.tapestry.ComponentResources | componentResources | 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. |
