在几个工作表中将HTML表导出为Excel

Question

我必须在一些工作表中将一些表导出到excel。

我在这个主题上使用了Axel的代码：Adding worksheet to the excel file using javascript

一切似乎都很好，但出口没有开始;浏览器控制台显示XML日志，我不知道如何解决这个问题。

我认为这个问题与HTML表有关。有人知道这个问题吗？

Here are a test for Axel's code

以下是他的表：

<table id="tbl1">
  <tr>
    <td>Name</td>
    <td>Birthday</td>
    <td>Amount</td>
    <td>Rebate (10%)</td>
  </tr>
  <tr>
    <td>Smith</td>
    <td data-type="DateTime" data-style="Date" data-value="1980-03-23">Mar 23 1980</td>
    <td data-type="Number" data-style="Currency" data-value="1234.56">$ 1,234.56</td>
    <td data-formula="=RC[-1]/10" data-type="Number" data-style="Currency">$ 123.45</td>
  </tr>
  <tr>
    <td>Doe</td>
    <td data-type="DateTime" data-style="Date" data-value="1978-11-05">Nov 05 1978</td>
    <td data-type="Number" data-style="Currency" data-value="2345.67">$ 2,345.67</td>
    <td data-formula="=RC[-1]/10" data-type="Number" data-style="Currency">$ 234.56</td>
  </tr>
</table>
<hr>
<table id="tbl2">
  <tr>
    <td>Product</td>
    <td>Price</td>
    <td>Available</td>
    <td>Count</td>
  </tr>
  <tr>
    <td>Bred</td>
    <td data-type="Number" data-style="Currency" data-value="1.89">$ 1.89</td>
    <td data-type="Boolean" data-value="1">yes</td>
    <td data-type="Number" data-value="123">123</td>
  </tr>
  <tr>
    <td>Butter</td>
    <td data-type="Number" data-style="Currency" data-value=".89">$ .89</td>
    <td data-type="Boolean" data-value="0">no</td>
    <td data-type="Number" data-value="0">0</td>
  </tr>
</table>


<button  onclick="tablesToExcel(['tbl1','tbl2'], ['Customers','Products'], 'TestBook.xls', 'Excel')">Export to Excel</button>
<button  onclick="tablesToExcel(['tbl1','tbl2'], ['Customers','Products'], 'TestBook.xls', 'Calc')">Export to Calc</button>

以下是构建HTML表格的代码摘录：

for(var j=0;j<nbData;j++){
if(j==0){
    /*Gerer le premier affichage (Entete tableau)*/
    affData += "<BR/><center><table id=\"tableToExport_"+i+"\" class=\"donnees\"><tr class=\"titre\"><td>"+xmlDoc.getElementsByTagName("data")[j].childNodes[0].firstChild.nodeValue+"</td><td></td></tr>"
}
var date = xmlDoc.getElementsByTagName("data")[j].childNodes[1].firstChild.nodeValue;
var val = xmlDoc.getElementsByTagName("data")[j].childNodes[2].firstChild.nodeValue;
affData += "<tr>";
    affData += '<td data-type="DateTime" data-style="Date" data-value="'+date.substring(0,date.length-7)+'">'+date.substring(0,date.length-7)+'</td>';
    //affData += '<td data-type="DateTime" data-style="Date" data-value="'+date.substring(0,date.length-16)+'">'+date.substring(0,date.length-16)+'</td>';
    affData += '<td data-type="Number">'+val+"</td>";
affData += "</tr>";
if(j==nbData-1){
    /*Gerer le dernier affichage (Fermer tableau)*/
    affData += "</table></center><BR/>";
}

}

这是要导出的表格之一：

<table id="tableToExport_0">
<tbody>
  <tr class="titre">
    <td>Title</td>
    <td></td>
  </tr>
  <tr>
    <td data-type="DateTime" data-style="Date" data-value="2015-01-21 00:03:59">2015-01-21 00:03:59</td>
    <td data-type="Number">71.0</td>
  </tr>
  <tr>
    <td data-type="DateTime" data-style="Date" data-value="2015-01-21 00:09:00">2015-01-21 00:09:00</td>
    <td data-type="Number">72.0</td>
  </tr>
  <tr>
    <td data-type="DateTime" data-style="Date" data-value="2015-01-21 00:14:00">2015-01-21 00:14:00</td>
    <td data-type="Number">65.0</td>
  </tr>
  <tr>
    <td data-type="DateTime" data-style="Date" data-value="2015-01-21 00:19:00">2015-01-21 00:19:00</td>
    <td data-type="Number">75.0</td>
  </tr>
</tbody>
</table>

拜托，怎么了？

[编辑] 这是我的完整代码：
