Problem in aligning table header with table body in extendeddatatable

[thejkmmav]

Hi I am using

<rich:extendedDataTable>

<rich:columns value="#{searchCriteriaBean.columnHeader}" >

    <f:facet name="header" >
                    <h:outputText value="#{columnD.headerName}" />
                </f:facet>
                <h:outputText value="#{rowdata.displayColumnData[ind].columnData}"

------

</rich:columns>

</rich:extendedDataTable>

The problem here is table header not algned with table body when the column text is too lengthy.

So how can i wrap the text?

I have tried

<style>
.extdt-cell {
    white-space: normal;
    }
</style>

which is not working?

Thanks in advance
