如题
ul.menu{ display: none; position: absolute; width: 200px; text-align: left; border: 1px solid #000; background-color: #fff; list-style: none; z-index: 9999;}ul.menu table{ vertical-align: top; line-height:18; font-size: 9pt; border-top: 1px solid #000; line-height: 18px; list-style:none; padding-left: 20px; overflow-y: visible; cursor: pointer; border: 0;}ul.menu table tr{ vertical-align: top; font-size: 9pt; border-top: 0px solid #000; list-style:none; padding-left: 2px; padding-top: 0px; background-color: #ADD8E6; cursor: pointer; border: 0;}ul.menu table td{ vertical-align: top; line-height:18; font-size: 9pt; border-top: 0px solid #000; line-height: 18px; list-style:none; padding-left: 2px; padding-top: 0px; background-color: #ADD8E6; overflow-y: visible; cursor: pointer; border: 0;}ul.menu table caption{ font-size: 9pt; background-color: #ADD8E6; border: 0;} 为什么就不能居左上显示呢，单元格里现在是水平居中左起显示
回复讨论(解决方案)
虽然有很多垃圾样式，不过总体看起来没什么问题，你可以尝试给td加个高，看是否是垂直居中
正常来讲vertical-align: top;已经可以控制居上
还有就是table一般在默认样式重置的会做如此设置
table { border-collapse:collapse; }
而border 边框会加在td上
我看着像是因为line-height的设置影响的。
line-height用于设置行内元素的高度，但同时也会使得行内元素的内容上下居中显示。
ul.menu table td{ vertical-align: top; line-height:18; //你这里用了两个line-height是个什么意思啊。 font-size: 9pt; border-top: 0px solid #000; line-height: 18px; //不带单位和带单位的line-height可是天差地别的，注意 list-style:none; padding-left: 2px; padding-top: 0px; background-color: #ADD8E6; overflow-y: visible; cursor: pointer; border: 0;} 这个地方，你可以试试把line-height去掉，如果想要控制td的显示高度，可以添加display:inline-block，height:18px；这样设置。
试试，有问题再说呗。
line-height:18px;
谢了，解决了。前台的人走了，后台兼前台，完全不了解。
最近还得多麻烦各位了
没问题，没问题

After reading it, you can easily deal with various caching problems, allowing your users to always experience the freshest content. Let’s talk about the basics first.
