CSS中三列布局的问题-问答-阿里云开发者社区-阿里云

问题描述
我现在有一个三列布局，暂且以左侧A、中间B和右侧C三个区间来表示。现有要求如下：

A的宽度固定，为150px
C的宽度根据内容自动撑开，也就是刚好包裹住其内容，右侧有15px的留白。
B的宽度自适应，文字内容居中

解决思路
利用CSS3的flex布局可以解决该问题，但是由于要支持IE8+，所以这种方法不太合适
利用圣杯布局或者淘宝UED提供的双飞翼布局，但是由于双飞翼布局针对固定宽度和或者流体宽度（百分比), 视乎不太适合现在的C宽度自动适应的问题。
利用display:table，可以支持IE8+，和思路2一样，C的宽度不是刚好包裹住的
不知道各位有没有什么更好的方法，我的测试代码如下

<!doctype html>
<html>

<head>
    <meta charset="utf-8">

</head>

<body>
