Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则， 并将Form-Item的prop属性设置为需校验的字段名即可
<el-form-item label="活动名称" prop="name"> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" 注1：有多个表单，怎么在提交进行区分？ 我们在rules这里写了对表单的验证规则，但是我们如何在methods里进行指定的表单进行认证， 所以我们一开始就在el-form里写了 ref="ruleForm"，我们在methods里就可以用 注2：清空表单验证信息 this.$refs[formName].resetFields();CUD 2.1 新增 2.2 添加修改/删除按钮 2.3 在上使用特殊的slot-scope 特性，可以接收传递给插槽的prop
