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:
