elementUI 的 el-row组件提供了rules属性来定制 各个el-form-item的验证规则

代码如下,其中form的 :model必须绑定一个对象，然后form-item prop属性绑定该对象下面的想要验证的属性，

注意！！！ prop指定的属性只能是对象的下一层属性 ,例如对象 var data = {name:"",sex:"",config:{set:"",get:""}}

当:model绑定为data时，form-item prop属性只能填name，sex，不能绑定config属性下面的set和get属性，即只能绑定一层属性，不能绑定多层下的属性，如果想要form-item prop想要绑定seth和get属性，可以设置 ：model=data.config，或者设置prop 为 config.set,config.get ，但此时绑定不了上一层的name和sex属性
