element-ui的el-table和el-form表单校验嵌套使用

在项目有遇到table中嵌套form，并且带有表单验证的需求，效果图如下：

刚开始el-form-item定义了静态prop（prop=“sn”），结果input填入值后错误提示一直存在，自定义校验的value也为undefined，然后经百度大神提点，得知出错在prop

• ⚠️应该写动态prop保证唯一性。

:prop="'monitorData.' + scope.$index + '.sn'" 

 

• ⚠️不只是el-form才配置，每一个el-form-item都要配置rules属性

• <el-form :model="monitorForm" :rules="monitorForm.monitorRules" ref="monitorForm">
    <el-table
        class="blue-theme add-virtual-table"
        empty-text="请 新增填写行 进行填写"
        :data="monitorForm.monitorData"
        style=" 100%;">
        <el-table-column
            type="index"
            align="center"
            width="50"/>
        <el-table-column
            prop="sn"
            label="SN">
            <template slot-scope="scope">
              <el-form-item

                  :rules="monitorForm.monitorRules.sn">
                  <el-input
                      class="light-blue-theme"
                      clearable v-model="scope.row.sn"
                      placeholder="请输入sn"/>
