Question

I need to create a table structured as shown below:

+----+--------+
| ID | Values |
+----+--------+
|  1 | val 1  |
+----+--------+
|    | val2   |
+----+--------+
|    | val 3  |
+----+--------+
|  2 | val 4  |
+----+--------+
|    | val 5  |
+----+--------+

i.e. the first column values may extend over multiple rows.

My JSF object is;

class abc {
    int id;
    String[] values;
}

I ended up using a PrimeFaces implementation of panelGrid:

<p:panelGrid>
    <p:row>
        <p:column rowspan="2">Header 1</p:column>
        <p:column>attrib 1 1</p:column>
        <p:column>arrtib 1 2</p:column>
    </p:row>
    <p:row>
        <p:column>attrib 2 1</p:column>
        <p:column>arrtib 2 2</p:column>
    </p:row>
</p:panelGrid>
