我得到一个类似的错误。问题是标题行不正确。当我执行下面的标题行时，我遇到的问题得到了解决。

<table id="example" class="table table-striped table-bordered" style="width:100%">
        <thead>
    <tr>
                <th colspan="6">Common Title</th>
            </tr>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Age</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>Tiger Nixon</td>
                <td>System Architect</td>
                <td>Edinburgh</td>
                <td>61</td>
                <td>2011/04/25</td>
                <td>$320,800</td>
            </tr>

我可能是由acolumns字段产生的。如上所述

aocolcolumns:如果指定了，则该数组的长度必须相等 到原始HTML表中的列数。在此处使用“null” 您希望只使用默认值并自动检测 选项。

然后必须像在Columns表中一样添加字段

...
aoColumnDefs: [
    null,
    null,
    null,
    { "bSortable": false },
    null,
],
...

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();

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!

供参考，数据表需要一个格式良好的表。它必须包含<thead>和<tbody>标签，否则将抛出此错误。还要检查确保包括标题行在内的所有行具有相同的列数。

以下将抛出错误(没有<thead>和<tbody>标签)

<table id="sample-table">
    <tr>
        <th>title-1</th>
        <th>title-2</th>
    </tr>
    <tr>
        <td>data-1</td>
        <td>data-2</td>
    </tr>
</table>

下面也会抛出一个错误(列数不等)

<table id="sample-table">
    <thead>
        <tr>
            <th>title-1</th>
            <th>title-2</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>data-1</td>
            <td>data-2</td>
            <td>data-3</td>
        </tr>
    </tbody>
</table>
