引导表，如何平等地对齐每个表？

Question

如下图所示，红线代表每个<td>的宽度不相等。我的目标是使每个<td>均匀对齐。我该怎么办？

CSS

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

代码

<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>

额外的宽度可能来自您那里的FontAwesome图标，默认情况下它们具有不同的宽度。可以通过将类fa-fw应用于每个图标来纠正此问题：

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

<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-fw fa-home fa-2x"></i><br>Home</a></td>
      <td><a href="#"><i class="fa fa-fw fa-bell fa-2x"></i><br>Notification</a></td>
      <td><a href="#"><i class="fa fa-fw fa-file-invoice-dollar fa-2x"></i><br>Transaction</a></td>
      <td><a href="#"><i class="fa fa-fw fa-search fa-2x"></i><br>Directory</a></td>
      <td><a href="#"><i class="fa fa-fw fa-newspaper fa-2x"></i><br>Ads</a></td>
      <td><a href="#"><i class="fa fa-fw fa-dollar-sign fa-2x"></i><br>Billing</a></td>
      <td><a href="#"><i class="fa fa-fw fa-plus fa-2x"></i><br>More</a></td>
      <td><a href="#"><i class="fa fa-fw fa-cogs fa-2x"></i><br>Setting</a></td>
    </tr>
  </table>
</div>

请记住，<td>单元格将自动扩展以填充其<tr>容器的可用宽度，并且具有较长文本的单元格将在这方面“想要”占据更多空间。如果要强制约束（或扩展）它们，只需给它们定义一个width。

在上面的示例中也可以看到，我声明每个单元格必须至少至少200px宽。
