如果你有'aoColumns'之类的表参数，也会发生这种情况:[..]]，它们与正确的列数不匹配。当从其他页面复制粘贴代码以快速启动数据表集成时，通常会出现这样的问题。

例子:

这行不通:

<table id="dtable">
    <thead>
        <tr>
            <th>col 1</th>
            <th>col 2</th>
        </tr>
    </thead>
    <tbody>
        <td>data 1</td>
        <td>data 2</td>
    </tbody>
</table>
<script>
        var dTable = $('#dtable');
        dTable.DataTable({
            'order': [[ 1, 'desc' ]],
            'aoColumns': [
                null,
                null,
                null,
                null,
                null,
                null,
                {
                    'bSortable': false
                }
            ]
        });
</script>

但这是可行的:

<table id="dtable">
    <thead>
        <tr>
            <th>col 1</th>
            <th>col 2</th>
        </tr>
    </thead>
    <tbody>
        <td>data 1</td>
        <td>data 2</td>
    </tbody>
</table>
<script>
        var dTable = $('#dtable');
        dTable.DataTable({
            'order': [[ 0, 'desc' ]],
            'aoColumns': [
                null,
                {
                    'bSortable': false
                }
            ]
        });
</script>

我在通过脚手架生成器创建的Rails视图中使用DOM数据时遇到了同样的问题。默认情况下，视图为最后三列(包含显示、隐藏和销毁记录的链接)省略<th>元素。我发现，如果我在<thead>内的<th>元素中为这些列添加标题，它就解决了这个问题。

I can't say if this is the same problem you're having since I can't see your html. If it is not the same problem, you can use the chrome debugger to figure out which column it is erroring out on by clicking on the error in the console (which will take you to the code it is failing on), then adding a conditional breakpoint (at col==undefined). When it stops you can check the variable i to see which column it is currently on which can help you figure out what is different about that column from the others. Hope that helps!

有<thead>和<tbody>与<th>和<td>相同的数字解决了我的问题。

我找到了一些“解决方案”。

这段代码不起作用:

<table>
<thead>
    <tr>
        <th colspan="3">Test</th>
    </tr>
</thead>
<tbody>
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
</tbody>

但这是可以的:

<table>
<thead>
    <tr>
        <th colspan="2">Test</th>
        <th></th>
    </tr>
</thead>
<tbody>
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
</tbody>

我认为，问题是，最后一个TH不能有colspan属性。

In my case, and using ASP.NET GridView, UpdatePanel and with DropDownList (with Chosen plugin where I reset value to zero using a Javascript line), I got this error and tried everything with no hope for days. The problem was that the code of my dropdown in code behind was as follows and when I select a value twice to apply its action to selected grid rows I get that error. I thought for days it's a Javascript issue (again, in my case) and finally the fix was giving zero for the drowpdown value with the update process:

  private void ddlTasks_SelectedIndexChanged(object sender, System.EventArgs e)
  {
     if (ddlTasks.SelectedValue != 0) {
        ChangeStatus(ddlTasks.SelectedValue);
        ddlTasks.SelectedValue = "0"; //// **This fixed my issue**
     }

     dvItemsGrid.DataSource = CreateDatasource();
     dvItemsGrid.DataBind();
     dvItemsGrid.UseAccessibleHeader = true;
     dvItemsGrid.HeaderRow.TableSection = TableRowSection.TableHeader;

  }

这是我的错:

     $('#<%= DropDownList.ClientID%>').val('0').trigger("chosen:updated").chosen();
