vue element-ui的el-table和el-form嵌套使用表单校验

表格是el-table自动获取的后台数据，每行都有el-input的验证，这样一个rules的规则就不能匹配到每一行，所以要是用动态的prop和rules规则

关键一

此处 data中定义的变量，params：表格数据，后台查询获得；paramsRules：校验规则

关键二

此处 :model、:rules

关键三

此处 :prop="'params.' + scope.$index + '.min'"和:rules="paramsForm.paramsRules.min"即动态对应上每行数据的校验规则

<template>
  <div>
    <el-form :model="paramsForm" ref="rForm" :rules="paramsForm.paramsRules">
      <el-table
        :data="paramsForm.params"
