结合element的rule表单校验，使用await获取promise的reject内容，使用try和catch方法

<el-form-item
  label
  :prop="'tableDataMidField.' + scope.$index + '.function2'"
  :rules="[{ required: true, message: '请输入', trigger: 'blur' }, {validator: validateTables, trigger: 'blur'}]"
>
  <el-input v-model="scope.row[v.prop]"></el-input>
</el-form-item>

    async validatorCommon(value, callback, params) {
      let response = null
      try {
        response = await parseFunction(params) //this.parseFunction(params)
        return callback();
      } catch (e) {
        return callback(new Error(`${e}`));
      }
    },
