Answer 1

绝对定位的元素根据具有定位上下文的最近父元素进行定位，如果没有，它将根据主体定位自身。

由于您要相对于悬停的 td 定位工具提示，因此您需要向td添加position:relative并稍微更改您的 js：

td{
 position: relative;   
}​
 $(".tip_trigger").hover(function () {
                    tip = $(this).find('.tip');
                    tip.css('top','-40px').show(); //Show tooltip
                }

看这里。

这并不完美，但这是您需要的方向。
