<%@include file="/WEB-INF/jsp/include/pagedirectives.jsp"%>

<div style="background: #D6E8FF; padding: 10px;" class="advanced_search">
<%@include file="/WEB-INF/jsp/include/page.topmessagebox.jsp"%>

<table class="form" cellspacing="0" id="requestSubmissionEform">

            <tr id="serviceTypeWithEform">
                <td class="label"><label for="${eformDetails.id}_0"><c:out

                    <td id="Col4" style="visibility: visible;"><input
                        id="eformDetail_${eformDetails.id}_4" class="eformDetail"
                        type="text" value="" name="form_4"></input></td>
                </c:if>
            </tr>

        </c:forEach>
        <c:if test="${empty eformDetailsList}">
            <tr id="serviceTypeWithNoEform">
                <td><b>There is no eform associated with this Service Type</b></td>
            </tr>
        </c:if>

    </tbody>
</table>

此页面将有 2 个按钮（上一页和下一页）。单击“下一步”时，我想将列标题更改为 6、7、8、9、10 等形式，以便进一步单击。请帮忙！

Answer 1

只需根据当前页面动态打印它们，从页面索引 0 开始。按每一个下一个按钮，页面索引

<tr>
    <th>Label</th>
    <th>Form ${(page * 5) + 1}</th>
    <th>Form ${(page * 5) + 2}</th>
    <th>Form ${(page * 5) + 3}</th>
    <th>Form ${(page * 5) + 4}</th>
    <th>Form ${(page * 5) + 5}</th>
</tr>

就会增加 1。（请注意，表格标题单元格将由，不是）
