我正在尝试从表转换为引导网格，以实现移动可比性。下面是它们在一个页面上的图片，但是尽管它们都遵循相同的css，bootstrap与table不在中心。有人能给我解释一下吗，因为这毫无意义。
谢谢你
桌子在上面，鞋带在下面
这是我的HTML

为了调试，首先我添加了以下内容，因为您的文本是白色的，边框为1px纯红，这样做很容易看出为什么它没有居中！检查链接
body {
background-color: gray;
}
* {
border: 1px solid red;
}
https://jsfiddle.net/dalinhuang/aLpv8k3f/4/
现在，正如你所看到的，它在正确的位置，这是因为
您只需将以下类添加到您的
Gold BS.fullwidth {
width: 100%;
}
好的，完整的解决方案，删除我们添加的调试内容：
https://jsfiddle.net/dalinhuang/aLpv8k3f/5/
另外，我认为你的星不在同一行，更新你的
<table class="fullwidth">来添加这个.glyphicon-star。.glyphicon-star {
font-size: 20px;
margin-top: -1px;
}
