ICEFaces: The columns component provides a dynamic model for adding and deleting columns at run time. It uses the standard var and value attributes. The columns component works in conjunction with the ice:dataTable. The headerClass and columnClasses defined on the dataTable component will be applied to all generated columns as it does on a single column. Examples | <ice:dataTable var="item" value="#{columnsBean.rowDataModel}" columnClasses="columnsColumn" > | <ice:columns value="#{columnsBean.columnDataModel}" var="column"> | <f:facet name="header"> | <ice:outputText value="#{column}" /> | </f:facet/> | <ice:outputText id="intCell" value="#{columnsBean.intValue}"/> | </ice:columns> | </ice:dataTable> The columns component can be used in conjunction with a column component (e.g.) <ice:dataTable var="item" value="#{columnsBean.rowDataModel}" columnClasses="columnsColumn" > | <ice:column> | <f:facet name="header"> | <ice:outputText value="id" /> | </f:facet/> | <ice:outputText value="#{item.id}"/> | </ice:column> | <ice:columns value="#{columnsBean.columnDataModel}" var="column"> | <f:facet name="header"> | <ice:outputText value="#{column}" /> | </f:facet/> | <ice:outputText value="#{columnsBean.intValue}"/> | </ice:columns> | </ice:dataTable> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082270#...
