${subBean.skill}

${rootBean.beanlastdate}

我得到的输出为：

但我不想打印第二行

我在谷歌上搜索了一下，发现我们连休息都写不出来；语句，我也不想使用任何类型的scriptlet。

在c:forEach标记上设置属性

<c:forEach var="rootBean" items="${vpaessbal}" status="rowStatus">...</c:forEach>

所以你会有

   <c:forEach var="rootBean" items="${vpaessbal}" status="rowStatus" >
    <c:if test="${rowStatus.count != 2}">
            <tr>

                    <br>
                    <br>

                    <td>${rootBean.beanprojname} <br>
                    <a href="">More Details</a></td>
                    <td>
                        <table border="1">
                            <tr>
                                <th>Skill Set</th>

                            </tr>


                            <c:forEach items="${rootBean.vpaerdclist}" var="subBean" varStatus="i">

                                    <tr>

                                    <td>${subBean.skill}</td>

                                    <td>${subBean.exp}</td>

                                    <td>${subBean.ncand}</td>

                                </tr>

                            </c:forEach>

                </tr>
               </c:if>
            </c:forEach>

我可能会感到困惑，但不是（ViewProjAssEmpBean s:vpaebal）的

。。。中断

相当于只显示

vpaebal[0]

ie，去掉循环，只显示集合的第一个元素？是的，你是对的。。我已经编辑了我的问题！

   <c:forEach var="rootBean" items="${vpaessbal}" status="rowStatus" >
    <c:if test="${rowStatus.count != 2}">
            <tr>

                    <br>
                    <br>

                    <td>${rootBean.beanprojname} <br>
                    <a href="">More Details</a></td>
                    <td>
