在我的情况下，这个错误发生，如果我使用表没有标题

              <thead>
                   <tr>
                       <th>example</th>
                  </tr>
              </thead>

我遇到了同样的问题，但我是动态生成表。在我的例子中，我的表缺少<thead>和<tbody>标签。

下面是我的代码片段，如果它对某人有帮助的话

   //table string
   var strDiv = '<table id="tbl" class="striped center responsive-table">';

   //add headers
   var strTable = ' <thead><tr id="tableHeader"><th>Customer Name</th><th>Customer Designation</th><th>Customer Email</th><th>Customer Organization</th><th>Customer Department</th><th>Customer ContactNo</th><th>Customer Mobile</th><th>Cluster Name</th><th>Product Name</th><th> Installed Version</th><th>Requirements</th><th>Challenges</th><th>Future Expansion</th><th>Comments</th></tr> </thead> <tbody>';


  //add data
  $.each(data, function (key, GetCustomerFeedbackBE) {
                            strTable = strTable + '<tr><td>' + GetCustomerFeedbackBE.StrCustName + '</td><td>' + GetCustomerFeedbackBE.StrCustDesignation + '</td><td>' + GetCustomerFeedbackBE.StrCustEmail + '</td><td>' + GetCustomerFeedbackBE.StrCustOrganization + '</td><td>' + GetCustomerFeedbackBE.StrCustDepartment + '</td><td>' + GetCustomerFeedbackBE.StrCustContactNo + '</td><td>' + GetCustomerFeedbackBE.StrCustMobile + '</td><td>' + GetCustomerFeedbackBE.StrClusterName + '</td><td>' + GetCustomerFeedbackBE.StrProductName + '</td><td>' + GetCustomerFeedbackBE.StrInstalledVersion + '</td><td>' + GetCustomerFeedbackBE.StrRequirements + '</td><td>' + GetCustomerFeedbackBE.StrChallenges + '</td><td>' + GetCustomerFeedbackBE.StrFutureExpansion + '</td><td>' + GetCustomerFeedbackBE.StrComments + '</td></tr>';
                        });

//add end of tbody
 strTable = strTable + '</tbody></table>';

//insert table into a div                 
   $('#divCFB_D').html(strDiv);
   $('#tbl').html(strTable);


    //finally add export buttons 
   $('#tbl').DataTable({
                            dom: 'Bfrtip',
                            buttons: [
                                'copy', 'csv', 'excel', 'pdf', 'print'
                            ]
                        });

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>
</tbody>
</table>

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>

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();

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>
