I have a table with header and data. When I am scrolling the header is also getting scrolled my code is as follows:

<div style="height:200px;overflow-x:auto;overflow-y:scroll;">
    <h:dataTable cellpadding="0" cellspacing="0" border="0" width="60%"
        headerClass="HeaderCellSorted" columnClasses="DataCell" rowClasses="OddRow,EvenRow" styleClass="SearchResults" footerClass="FooterCell" 
        id="userListTable" value="#{pc_WorkInProgressUserGrid.userGridModel.rebalanceByUserList}" var="userGridDO">
        <h:column id="userNameColumn">
            <f:facet name="header">
                <h:outputLink id="userNameColumnLink" styleClass="Header" value="#" onclick="refreshUserGrid('DISPLAYNAME')">
                    <h:outputText id="userNameColID" styleClass="outputText" value="User"/>

Any suggestion would be helpful.
