You have to code the table header separately, above <h:dataTable>. Providing the columnclass and style of the header of your dataTable.

Here is an example:

                <h:panelGrid id="panel" columns="4" columnClasses="rTypeColumn1,rTypeColumn2,rTypehColumn3,rTypeColumn4" styleClass="data-tableheader">
                    <h:outputLabel value="Column Name 1" />
                    <h:outputLabel value="Column Name 2" />
                    <h:outputLabel value="Column Name 3" />
                    <h:outputLabel value="Column Name 4"/>
                </h:panelGrid>

               <div class="scrollable">
                                <h:dataTable id="table" value="#{yourbean.list}"  var="data" cellspacing="0" columnClasses="rTypeColumn1,rTypeColumn2,rTypeColumn3,rTypeColumn4" width="100%" styleClass="data-table">
                                    <h:column>#{data.column1}</h:column>
                                    <h:column>#{data.column2}</h:column>
                                    <h:column>#{data.column3}</h:column>
                                    <h:column>#{data.column4}</h:column>
                                </h:dataTable>
                </div> 

Rest is all about CSS you use. Alternatively, if you can use Richfaces, it provides scrollable datatable, core JSF datatable is fairly limited, its all what you can do with it.

You could use IceFaces 1.8, a JSF component system suitable for JSF 1.1. It contains a scrollbar for dataTable
