JavaServer Faces

Name

<h:column>

Synopsis

This action represents an instance of the component type registered with the type ID javax.faces.Column (by default, an instance of the javax.faces.component.UIColumn class). A component of this type is rendered by its parent so the action doesn’t associate the component with a renderer.

A column component is used typically as a child of a javax.faces.component.UIData component and represents a single column of tabular data. It can be equipped with a header and a footer facet for a column header and footer. Its children are used to process the column’s data.

Syntax

<h:column [id="id"] [binding="componentBinding"] [rendered="true|false"] >
  [<f:facet name="header">...</facet>]
  [<f:facet name="footer">...</facet>]
  JSF component action elements
</h:column>
