 text-align: center;

 <tr>
  <th>编号</th>
  <th>名称</th>
  <th>品牌</th>

  <th>操作</th>
 </tr>
 <tr v-for="val in items">
  <td>{{val.id}}</td>
  <td>{{val.name}}</td>
  <td>{{val.pinpai}}</td>
  <td>{{val.price}}</td>
  <td>
  
  <button v-bind:disabled="val.count === 0" @click="val.count-=1">-</button>
  {{val.count}}
  <button @click="val.count+=1">+</button>
  
  </td>
  <td>
  <button v-on:click="val.count = 0">移除</button>
  </td>
  
 </tr>

 你所需要支付总额为：${{totalPrice()}}

 methods:{
  totalPrice:function(){
  var totalPri = 0;
  //总价等于数量乘以数量
