推荐答案

您必须在<h:dataTable>上方单独编码表头. 提供数据表标题的columnclass和样式.

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

这里是一个例子:

                <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与您使用的CSS有关. 另外，如果您可以使用 Richfaces ，它提供了可滚动的数据表，核心的JSF数据表相当有限，您可以使用它进行所有操作.

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.
