Attributes
Name | Required | Request-time | Type | Description
binding | false | false | `java.lang.String` | The value binding expression linking this component to a property in a backing bean
colspan | false | false | `java.lang.String` | This is exactly an html colspan attribute. Due to the iterative nature of the table body, this attribute is not suitable inside the body of the dataTable. So this attribute will only be apply on the columns that are descendent of the colmnGroup component.
groupOn | false | false | `java.lang.String` | The groupOn attribute, enables the application to show the one to many relationship in the tabular format. Only the distinct values will be rendered for the grouped column, and its rowspan value will be set to its none distinct count. Note: Application must provide the sorted data for the grouped column. This attribute is just for the layout, it does not have any effect on the underlying dataModel. <ice:dataTable var="employee" .. > <ice:column groupOn="#{employee.deptName}" > <ice:outputText value="#{employee.deptName}"/> </ice:colum> <ice:column > <ice:outputText value="#{employee.name}"/> </ice:colum> ..... </ice:dataTable .. >
id | false | false | `java.lang.String` | The component identifier for this component. This value must be unique within the closest parent component that is a naming container.
rendered | false | false | `java.lang.String` | Flag indicating whether or not this component should be rendered (during Render Response Phase), or processed on any subsequent form submit.
renderedOnUserRole | false | false | `java.lang.String` | If user is in given role, this component will be rendered normally. If not, nothing is rendered and the body of this tag will be skipped.
rowspan | false | false | `java.lang.String` | This is exactly an html rowspan attribute. Due to the iterative nature of the table body, this attribute is not suitable inside the body of the dataTable. So this attribute will only be apply on the columns that are descendent of the colmnGroup component. Hint: The groupOn attribute might give you the result, which you need from the rowspan inside the body of the table.
style | false | false | `java.lang.String` | CSS style(s) to be applied when this component is rendered.
styleClass | false | false | `java.lang.String` | Space-separated list of CSS style class(es) to be applied when this element is rendered. This value must be passed through as the "class" attribute on generated markup. If this attribute is defined on the column, the new styleClass will be extending the existing styleClasses.
