 <td>$100</td>
 </tr>
 <tr>
 <td>January</td>
 <td>$100</td>
 </tr>
 </tbody> 
 </table>
 </div>
 </div>
</body>
</html>

CSS:

.scroll-body{
 display: inline-block;
}
.scroll-container{
 text-align: center;
}
#scroll-table{
 border: 1px solid;
 border-collapse: collapse;
 width: 200px;
 height: 200px;
 overflow: auto;
 display: block;
}

JS:

$(function () {
 $('#scroll-table').scroll(function (e) {
 var pagination = {
 page: 0,
 pageSize: 20
 };
 //滚动条位置 
 var scrollTop = $('#scroll-table').scrollTop();

 //可视窗口的高度 
 var viewportHeight = $('#scroll-table').height();

 //整个页面可以滚动的高度 
 var scrollHeight = $('#scroll-table')[0].scrollHeight;

 //“如果滚动条的位置”+“可视窗口的高度”=“整个页面可以滚动的高度”，那么就调用相应的函数加载数据 
 if (Math.round(scrollTop + viewportHeight) == scrollHeight) {
 var tr = $('<tr><td> good </td> <td> nice </td> /tr>');
 $('#scroll-tbody').append(tr);

 /*
 * pagination.page += 1;
 * dataAjax(pagination); //这里做第二页的数据请求并添加进表格 
 */
 }
 });
})
