我想显示一个 40 列和 1000 行的可滚动表格。

我使用rich:extendedDataTable了（我使用的是richfaces 4）clientRows="20"，但是我得到了一个有20行的表，当我滚动时，只是这些行被更新了，我没有得到新的行！

在此处输入图像描述

xHTML

            <rich:extendedDataTable id="idList"
                value="#{declarationReglementaireModel.detailCurrentDecReg.decReg.listLigneTa3SDTO}"
                var="ligneTA3" frozenColumns="2" style="height:300px; width:800px;"
                selectionMode="none" clientRows="15">

                <rich:column width="35px">
                    <h:panelGrid columns="1" cellpadding="2">
                        <h:commandLink action="#{rechercheDecRgltCtrl.afficherDetail}"
                            class="lien_detail">
                            <span class="icone icone-edit icone-align-center" />
                            <f:setPropertyActionListener
                                target="#{declarationReglementaireModel.detailCurrentDecReg.decReg.listLigneTa3SDTO}"
                                value="#{ligneTA3}" />
                        </h:commandLink>

设置clientRows您的属性<rich:extendedDataTable/>以指定在初始页面加载时要加载到客户端的初始行数。同一数据表的后续滚动将使用相同的数字增加可用的行数。

     <rich:extendedDataTable value="#{bean.items}" clientRows="15"/>

这种用法的前提是整个数据集已加载到服务器端。

如果您需要对服务器端的数据加载进行更细粒度的控制，您应该实现一个ExtendedDataModel来控制数据加载。
