Bootstrap表，如何均衡对齐每个 <td> ？

Question

正如您在下图所示，红线表示每个<td>宽度不等。 我的目标是使每个<td>均匀对齐。 我怎么做？

CSS

.stickyFooter {
            background: #c1c1c1;
            position: fixed;
            left: 0;
            right: 0;
            bottom: 0;
            height: 50px;
            font-size: 13px;
        }

码

<div class="stickyFooter wrap visible-sm visible-xs table-responsive" style="margin-bottom: 0px; border: none;">
<table class="table">
    <tr align="center">
        <td><a href="#"><i class="fa fa-home fa-2x"></i><br>Home</a></td>
        <td><a href="#"><i class="fa fa-bell fa-2x"></i><br>Notification</a></td>
        <td><a href="#"><i class="fa fa-file-invoice-dollar fa-2x"></i><br>Transaction</a></td>
        <td><a href="#"><i class="fa fa-search fa-2x"></i><br>Directory</a></td>
        <td><a href="#"><i class="fa fa-newspaper fa-2x"></i><br>Ads</a></td>
        <td><a href="#"><i class="fa fa-dollar-sign fa-2x"></i><br>Billing</a></td>
        <td><a href="#"><i class="fa fa-plus fa-2x"></i><br>More</a></td>
        <td><a href="#"><i class="fa fa-cogs fa-2x"></i><br>Setting</a></td>
    </tr>
</table>

附加宽度可能来自您在那里的FontAwesome图标，默认情况下宽度不同。 这可以通过将类fa-fw应用于每个图标来纠正：

 td { border: 1px solid black; min-width: 200px; }

请记住， <td>单元格将自动扩展以填充其<tr>容器的可用宽度，而具有较长文本的单元格将“希望”在这方面占据更多空间。 如果你想强制约束（或扩展）它们，只需给它们一个定义的width 。

这也可以在上面的例子中看到，其中我声明每个单元必须至少200px宽。
