可以通过传入参数的方式获取到该行数。在定义checkPass方法时，可以在参数中传入当前表单项的值和当前表单项的索引。例如：

checkPass(rule, value, callback, index) {
  // index即为当前表单项的索引
  // 可以根据索引来获取到该行数
  const row = this.list[index];
  // ...
}

在模板中调用该方法时，需要将当前表单项的索引作为参数传入：

<el-form-item
  :prop="'list.' + scope.$index + '.controlok'"
  :rules="fromDataRules.controlok"
>
  <el-input
    v-if="scope.row.controluse === 'S2F21'"
    :disabled="
      scope.row.iscontrol === false ||
      scope.row.iscontrol == null ||
      scope.row.iscontrol == ''
    "
    v-model="scope.row.controlok"
    filterable
    clearable
    :class="{ 'is-invalid': errors['list.' + scope.$index + '.controlok'] }"
  />
  <el-select
    v-else
    v-model="scope.row.controlok"
    :disabled="
      scope.row.iscontrol === false ||
      scope.row.iscontrol == null ||
      scope.row.iscontrol == ''
    "
    :placeholder="t('web_ems_tip_pleaseInput')"
    filterable
    clearable
    :class="{ 'is-invalid': errors['list.' + scope.$index + '.controlok'] }"
  >
    <el-option
      v-for="item in identifyingList"
      :key="item.id"
      :label="item"
      :value="item"
    />
  </el-select>
</el-form-item>

可以看到，在el-input和el-select中都有一个:class绑定，用来判断当前表单项是否验证通过，如果不通过，则添加一个is-invalid类名，可以在样式中对该类名进行样式设置。同时，在prop中也需要将当前表单项的索引作为属性名的一部分。这样，在定义checkPass方法时，就可以通过该属性名来获取到该行数的值。
