数据表：仅加载可见列

Question

我正在尝试使用DataTables和AJAX构建一个大型的交互式表（10,000个条目x 30列）。默认情况下，许多列都是隐藏的，但是AJAX请求仍然会加载数据。

是否可以只加载可见列中的数据？

一个简短的例子：

data_table = $('#table').DataTable({
    "processing": true,
    "serverSide": true,
    "ajax": "http://127.0.0.1:8000/my/datatable/data/",
    columnDefs: [
        {title: 'Identifier', name: 'identifier', targets: [0]},
        {title: 'Old Identifier', name: 'old_identifier', targets: [1], visible: false},
        {title: 'Geographical Name', name: 'geographical_name', targets: [2], visible: false},
        {title: 'Isolation Date', name: 'isolation_date', targets: [3], visible: false},
        {title: 'Contaminated', name: 'contaminated', targets: [4], visible: false}
    ]
});

DataTables请求（针对隐藏的col 1进行了剪切）：

columns[1][data]=1
columns[1][name]=old_identifier
columns[1][searchable]=true
columns[1][orderable]=true
columns[1][search][value]=
columns[1][search][regex]=false

返回的内容：

{"draw": 1, "recordsTotal": 8993, "recordsFiltered": 25, "data": [["xyz-1c-1i-1.1", "xyz", "Switzerland", "2019-06-13", "False"], ... ], "result": "ok"}
