通过使用 columns.dataDT 选项用于告诉Datatables找到每一列的数据源对象中对应的属性。

下面例子的数据模型如下:
{ "name": "Tiger Nixon", "position": "System Architect", "salary": "$3,120", "start_date": "2011/04/25", "office": "Edinburgh", "extn": "5421" }

Name Position Office Extn. Start date Salary
Name Position Office Extn. Start date Salary
$(document).ready(function() {
    $('#example').DataTable( {
        "ajax": "data/objects.txt",
        "columns": [
            { "data": "name" },
            { "data": "position" },
            { "data": "office" },
            { "data": "extn" },
            { "data": "start_date" },
            { "data": "salary" }
        ]
    } );
} );
<table id="example" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Extn.</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </thead>

        <tfoot>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Extn.</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </tfoot>
    </table>
