如何在数据表中进行服务器端排序

Question

我在我的一个项目中使用了数据表，所有的东西都工作正常，除了订购，我们想使用服务器端排序，我尝试了很多例子，但它不适合我，任何人都可以帮我做排序，我遇到了这个问题，这是我的代码

episodes_data_table = $('#episodes_table').DataTable({
        "processing": true,
        "serverSide": true,
        "pageLength": 20,
        "dom": 'trip<"clear">',
        //"dom": 'trilp<"clear">',
        "aaSorting": [[0, "desc"]],
        "ajax": {
            type: "post",
            url: "<?php echo base_url(); ?>billing/get_episodes_data",
            data: function (d) {
                return jQuery.extend({}, d, {
                    "branch_id": current_branch_id,
        "month": $(".month-filter-input").val(),
        "year": $(".year-filter-input").val(),
                });
            }
        },
        "fnDrawCallback": function (oSettings) {
        },
        "columnDefs": [
            {
                "data": "ID",
                "render": function (data, type, row) {
