这是一个普通的表格，border=1，每个td都会有边框。
放手机里，table的左右边框明显有点多余且不美观。
那么如何去掉呢？
因为表格边框最终还是取决于td的。操作整个table的边框无法实现效果。
实现思路如下：
1、table的边框只留上边框和下边框
.table{ border-top: 1px solid #e8e8e8; border-bottom:1px solid #e8e8e8;}2、th或td的边框最左边不要
.table td,.table th{ ??border:1px solid #e8e8e8; border-left:none;}3、这时候表格最右边还有边框，可以用这个去除
.table tr th:last-child{border-right:none;}.table tr td:last-child{border-right:none;}最终的效果，table左边和右边的边框去除了：
