效果图：

HTML中无需添加额外的一列来表示复选框，而是由JS完成，所以正常的表格布局就行了：

[html] view plain copy

<table class="table table-bordered table-hover">
<thead>
<tr class="success">
<th>类别编号</th>
<th>类别名称</th>
<th>类别组</th>
<th>状态</th>
<th>说明</th>
</tr>
</thead>
<tbody>
<tr>
<td>C00001</td>
<td>机车</td>
<td>机车</td>
<td>有效</td>
<td>机车头</td>
</tr>
<tr>
<td>C00002</td>
<td>车厢</td>
<td>机车</td>
<td>有效</td>
<td>载客车厢</td>
</tr>
</tbody>
</table>

重点是JS的实现。复选框很小，不容易点到，所以点击每一行也可以选中该行，并用高亮一些CSS样式表示。点击复选框所在单元格也能选中复选框。下面是完整代码和注释说明：
