Datatable headerRow expanded attribute

[PlassJ]

While using the Datatable with expandableRowGroups, it would be really nice to control the togglestate of each headerRow.

I would like to suggest an expanded attribute for headerRow, see sample XHTML.

Sample XHTML:

<p:dataTable var="car" value="#{dtRowGroupView.cars}" sortBy="#{car.brand}" expandableRowGroups="true">
        <p:headerRow expanded="#{car.brand eq 'BMW'}" >
            <p:column colspan="3">
                <h:outputText value="#{car.brand}" />
            </p:column>
        </p:headerRow>
        <p:column headerText="Year">
            <h:outputText value="#{car.year}" />
        </p:column>
</p:dataTable>`

@PlassJ , I see you closed this request. Any particular reason why? I thought it was a good suggestion, and I'd like to see it added as well.
