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：
1 <table class="table table-bordered table-hover"> 2 <thead> 3 <tr class="success"> 4 <th>类别编号</th> 5 <th>类别名称</th> 6 <th>类别组</th> 7 <th>状态</th> 8 <th>说明</th> 9 </tr> 10 </thead> 11 <tbody> 12 <tr> 13 <td>C00001</td> 14 <td>机车</td> 15 <td>机车</td> 16 <td>有效</td> 17 <td>机车头</td> 18 </tr> 19 <tr> 20 <td>C00002</td> 21 <td>车厢</td> 22 <td>机车</td> 23 <td>有效</td> 24 <td>载客车厢</td> 25 </tr> 26 </tbody> 27 </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：
