Question

我正在使用Spring MVC和DataTable with jQuery来制作相关内容。

当没有数据可用时，我收到以下错误。

DataTables warning (table id='results'): Requested unknown parameter '1' from the data source for row 0

我在互联网上搜索，发现列数可能不匹配，但事实并非如此。但是，有时，数据为空/空，因此在UI中无需呈现任何内容。在这种情况下，我们甚至不显示表格。

但是这个错误始终存在。我刚开始使用DataTables并使用默认行为：

jq(document).ready( function(){
        jq("#results").dataTable();          
    });

我的表格代码如下：

<table border="1" style="font-size:12px;width: 868px; table-layout: fixed; word-wrap: break-word;border-collapse: collapse" id='results'>
<thead>
   <tr>
    <th>Batch Name</th>
    <th>Batch User</th>
    <th>Total URL Count</th>
    <th>Submitted URL Count</th>
    <th>Processed URL Count</th>
    <th>Submission Time</th>
    <th>Batch Status</th>
    <th>Download Link</th>
  </tr>
 </thead>
  <tbody id="orderbody">
   <tr id="pattern" style="display:none" >
    <td width="15%"><span  id="ibatchName">Batch Name</span></td>
    <td width="15%"><span  id="ibatchUser">Batch User</span></td>
    <td width="11%"><span  id="iTotalUrlCount" >Total URL Count</span></td>
    <td width="11%"><span  id="iSubmittedURLCount" >Submitted URL Count</span></td>
    <td width="11%"><span  id="iProcessedURLCount">Processed URL Count</span></td>
    <td width="11%"><span  id="iSubmissionTime" >Submission Time</span></td>
    <td width="11%"><span  id="ibatchStatus" >Batch Status</span></td>
    <td width="15%"><span  id="iDownloadLink" >Download Link</span></td>
    </tr>

    <c:choose>
    <c:when test="${  not empty batches}">
    <c:forEach var='batchDetail' items='${batches}'>
     <tr id="pattern0">
    <td>${batchDetail.batchName}</td>
    <td>${batchDetail.batchUser}</td>
    <td>${batchDetail.totalUrlCount}</td>
    <td>${batchDetail.submittedUrlCount}</td>
    <td>${batchDetail.processedUrlCount}</td>
    <td>${batchDetail.submissionTimeFormatted}</td>
    <td>${batchDetail.batchStatus}</td>
    <td>${batchDetail.downloadLink}</a></td>
   </tr>
    </c:forEach>    
    </c:when>

    <c:otherwise>
    <tr id="pattern0">
    <td colspan="8"><span class="batch_not_found">You are not authorized to see any of the batches. </span></td>
    </tr>
    </c:otherwise>
</c:choose>
   </tbody>   
  </table>

我该怎么办？有没有办法在没有提取数据时禁用此警告？

谢谢，

我自己得到了答案！

<tr id="pattern0">
    <td colspan="8"><span class="batch_not_found">You are not authorized to see any of the batches. </span></td>
    </tr>

是个问题。 DataTable无法呈现它。把它移到桌子外面就可以了。
