Ajax：更新并添加到表

I have an html table as such

<table>
    <tr id="headers">
        <td>Name</td>
        <td>Last Communicated</td>
        <td>Status</td>
    </tr>
    <tr id="data">
        <td id="name"></td>
        <td id="lastCom"></td>
        <td id="status"</td>
    </tr>
</table>

I have an ajax call that gets the data from an SQL database and returns a list of values. How can I use the data returned from Ajax to update the table and add an entry if the list has grown?

Thanks!

 $.ajax({
            type: 'post',
            datatype: "json",
            url: url,//Here are the background methods
            data: data,
            success: function (msg) {
               //Requery your query list statement
            }
        });
