Grouping columns under a single header in JSF

Question

Is there a way using JSF to group two or more columns under a single parent column in JSF? I have a dataTableEx with hx:columnEx columns inside of it. What I want is something like this:

 [MAIN HEADER FOR COL1+2   ][Header for Col 3+4]

 [ COL1 Header][COL2 Header][COL3    ][COL 4   ] 

 Data          Data             Data     Data

 Data          Data             Data     Data

 Data          Data             Data     Data

 Data          Data             Data     Data

Data Data Data Data

Thanks

You can probably achieve what you want with the table header, a panelGrid and a little CSS.

<style type="text/css">
.colstyle {
    width: 25%
}
</style>
</head>
<body>

<f:view>
    <h:dataTable border="1" value="#{columnsBean.rows}" var="row"
        columnClasses="colstyle">
        <f:facet name="header">
            <h:panelGrid columns="2" border="1" style="width: 100%">
                <h:outputLabel style="width: 100%" value="MAIN HEADER FOR COL1+2" />
                <h:outputLabel style="width: 100%" value="MAIN HEADER FOR COL3+4" />
            </h:panelGrid>
        </f:facet>
        <h:column>
            <f:facet name="header">
                <h:outputText value="COL1 Header" />
            </f:facet>
            <h:outputLabel value="#{row.col1}" />
        </h:column>
        <h:column>
            <f:facet name="header">
                <h:outputText value="COL2 Header" />
            </f:facet>
            <h:outputLabel value="#{row.col2}" />
        </h:column>
        <h:column>
            <f:facet name="header">
                <h:outputText value="COL3 Header" />
            </f:facet>
            <h:outputLabel value="#{row.col3}" />
        </h:column>
        <h:column>
            <f:facet name="header">
                <h:outputText value="COL4 Header" />
            </f:facet>
            <h:outputLabel value="#{row.col4}" />
        </h:column>
    </h:dataTable>
</f:view>

Your best bet is likely to use nested tables for the first header (first header in the outer table, and your second header and data inside a nested table) so that it looks like two headers.

Nesting JSF dataTables is a bad idea. – McDowell Nov 05 '08 at 17:35
the outer table wouldn't be a JSF Data Table, just the inner one. The outer one would just display the column headings you want. – Elie Nov 05 '08 at 17:44

Maybe you can have a look to advanced components libraries, such as RichFaces that offer more complex structures for datatables, like in this example.
