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：

<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：
