看起来你可以使用 API 函数来

It looks as if you could use the API functions to

• 清除表格 ( fnClearTable )
• 向表中添加新数据 (fnAddData)
• 重绘表格 ( fnDraw )

我猜您正在使用 DOM 数据源(用于服务器端处理)生成您的表格.一开始我并没有真正理解这一点，所以我之前的答案对此不起作用.

I guess you're using the DOM Data Source (for server-side processing) to generate your table. I didn't really get that at first, so my previous answer won't work for that.

在不重写服务器端代码的情况下使其工作:

To get it to work without rewriting your server side code:

您需要做的是完全删除旧表(在 dom 中)并将其替换为 ajax 结果内容，然后重新初始化数据表:

What you'll need to do is totally remove the old table (in the dom) and replace it with the ajax result content, then reinitialize the datatable:

// in your $.post callback:

function (data) {

    // remove the old table
    $("#ajaxresponse").children().remove();

    // replace with the new table
    $("#ajaxresponse").html(data);

    // reinitialize the datatable
    $('#rankings').dataTable( {
    "sDom":'t<"bottom"filp><"clear">',
    "bAutoWidth": false,
    "sPaginationType": "full_numbers",
        "aoColumns": [ 
        { "bSortable": false, "sWidth": "10px" },
        null,
        null,
        null,
        null,

        null,
        null,
        null,
        null,
        null
        ]

    } 
    );
}
