一些建议：
1、一个row为一行，一行最多分为12份，栅格只负责布局，class不要混用，class功能分开；
2、嵌套时col的直接父级元素只能是row;
3、布局里字段的写法，个人建议：
xxxxxxxxxx1
<div class="field-margin">2
<label for="user_name" string="姓名"/>3
<field name="user_name"/>4
</div>已复制
用个div包裹的目的是样式好调整，然后整个字段我用class(field-margin)加了点外边距
因为odoo自身集成了bootstrap，布局我们建议用bootstrap栅格系统布局。具体用法请参考bootstrap官网(https://v3.bootcss.com/css/#grid)
