vue elementUI 表单校验（数组多层嵌套）

<div v-for="(item,index) in dataFields.list :key="index">
    <el-form-item label="name" :prop="`list[${index}].name`" :rules="{ required: true, message: 'Required', trigger: 'blur' }">
       <el-input placeholder="name" v-model="item.name"></el-input>
   </el-form-item>
</div>
