正交数据,这个直译过来不怎么理解,找了些资料还是不怎么理解,贴单一句英文解释( 地址
In computer terminology, something - such as a programming language or a data object - is orthogonal if it can be used without consideration as to how its use will affect something else.

该例子的数据模型如下:

{
    "name":    "Tiger Nixon",
    "position":   "System Architect",
    "salary":    "$3,120",
    "start_date": {
        "display": "Mon 25th Apr 11",
        "timestamp": "1303682400"
    },
    "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/orthogonal.txt",
        columns: [
            { data: "name" },
            { data: "position" },
            { data: "office" },
            { data: "extn" },
            { data: {
                _:    "start_date.display",
                sort: "start_date.timestamp"
            } },
            { 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>
