el-form循环生成el-form-item校验失败原因_el-table-column 嵌套 el-form-item 校验 不生效

划重点：
:prop="‘specificationsCopy.’+scope.$index+’.name’"
:rules=“rules.name”

如果:rules=“rules.name” 换成required就会报错xxx is required

<el-form-item label="商品规格:" required>
            <div class="table">
              <el-table :data="ruleForm.specificationsCopy" row-key="skuId" border style="width: 100%" :header-cell-style="{ background: '#F7F7F7' }">
                <el-table-column prop="date" label="商品规格" header-align="center">
                  <template slot="header">
