如图，实现以下效果
通过点击新增就会新增一个表单，删除会删除最后一个表单，也可以指定删除哪个表单
代码实现
<el-form ref="shopArr" :model="shopArr" :rules="shopRules">
<table v-for="(item,index) in shopArr" :key="index" class="addTableShop">
<tr>
<td class="addTable-td1"><div class="table-item"><el-form-item label="1:" prop="settledPlatfoem" label-width="120px" /></div></td>
<td class="addTable-td2">
<el-radio-group v-model="item.settledType">
<el-radio :label="1">淘宝</el-radio>
<el-radio :label="2">京东</el-radio>
<el-radio :label="3">天猫</el-radio>
<el-radio :label="4">拼多多</el-radio>
<el-radio :label="5">其他
<input v-if="item.settledType === 5" v-model="item.settledPlatfoem" placeholder="请输入其他平台" style="width: 105px; margin-left: 10px"/>
</el-radio>
</el-radio-group>
</td>
<td class="addTable-td1"><div class="table-item"><el-form-item label="2:" prop="shopName" label-width="120px" /></div></td>
<td class="addTable-td2"><el-input v-model="item.shopName" /></td>

</table>
<el-button type="text" style="float: right" size="small" @click="addShop">新增</el-button>
<el-button type="text" style="float: right" size="small" @click="deleteShop">删除</el-button>
</el-form>

const item = {
settledType: '',
settledPlatfoem: '',
shopName: '',
shopUrl: '',
operatingLicense: ''
}
this.shopArr.push(item)
}，
// 删除表单
deleteShop() {
