两组不同的数据，在input type=checkbox时 v-model自动关联。

当我点击item1或者item2的input时 v-model同时绑定了它们俩

<table>
 <tr v-for="item1 in list1" :key="item1.index">
   <td>{{item1.parentProductName}}</td>
   <td>{{item1.productName}}</td>
   <td><input type="checkbox" v-model="item1.status" :checked="item1.status" @click="item1.status = !item1.status"></td>
 </tr>
</table>
<table>
 <tr v-for="item2 in list2" :key="item2.index">
   <td>{{item2.parentProductName}}</td>
   <td>{{item2.productName}}</td>
   <td><input type="checkbox" v-model="item2.status" :checked="item2.status" @click="item2.status = !item2.status"></td>
 </tr>
</table>
