我对数据表有一个问题。我也浏览了这个链接,但没有任何结果。我已经包括了将数据直接解析到DOM中的所有先决条件。

脚本

$(document).ready(function() {
  $('.viewCentricPage .teamCentric').dataTable({
    "bJQueryUI": true,
    "sPaginationType": "full_numbers",
    "bPaginate": false,
    "bFilter": true,
    "bSort": true,
    "aaSorting": [
      [1, "asc"]
    ],
    "aoColumnDefs": [{
      "bSortable": false,
      "aTargets": [0]
    }, {
      "bSortable": true,
      "aTargets": [1]
    }, {
      "bSortable": false,
      "aTargets": [2]
    }],
  });
});

对我来说,这个问题与上面给出的答案略有不同。对我来说,HTML标记很好,但是javascript中的一列缺失了,并且与HTML不匹配。

i.e.

<table id="companies-index-table" class="table table-responsive-sm table-striped">

                            <thead>
                            <tr>
                                <th>Id</th>
                                <th>Name</th>
                                <th>Created at</th>
                                <th>Updated at</th>
                                <th>Count</th>
                            </tr>
                            </thead>
                            <tbody>
                            @foreach($companies as $company)
                                <tr>
                                    <td>{{ $company->id }}</td>
                                    <td>{{ $company->name }}</td>
                                    <td>{{ $company->created_at }}</td>
                                    <td>{{ $company->updated_at }}</td>
                                    <td>{{ $company->count }}</td>
                                </tr>
                            @endforeach
                            </tbody>
                        </table>

我的脚本:

<script>
        $(document).ready(function() {
            $('#companies-index-table').DataTable({
                serverSide: true,
                processing: true,
                responsive: true,
                    ajax: "{{ route('admincompanies.datatables') }}",
                columns: [
                    { name: 'id' },
                    { name: 'name' },
                    { name: 'created_at' },
                    { name: 'updated_at' },     <-- I was missing this line so my columns didn't match the thead section.
                    { name: 'count', orderable: false },
                ],
            });
        });
    </script>

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'
                            ]
                        });

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>

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>

如何在。net MVC视图中成功地渲染一个数据表,这个问题让我抓狂。这工作:

 **@model List<Student>
 @{
    ViewData["Title"] = "Index";
}
 <h2>NEW VIEW Index</h2>
 <table id="example" class="display" style="width:100%">
   <thead>
   <tr>
   <th>ID</th>
    <th>Firstname</th>
    <th>Lastname</th> 
  </tr>
  </thead>
  <tbody>
@foreach (var element in Model)
{
    <tr>
    <td>@Html.DisplayFor(m => element.ID)</td>
    <td>@Html.DisplayFor(m => element.FirstName)</td>
    <td>@Html.DisplayFor(m => element.LastName)</td>
    </tr>

}
</tbody>
</table>**

JS文件中的脚本:

**$(document).ready(function () {
    $('#example').DataTable();
});**

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!
