vue如何實現(xiàn)商品列表的添加刪除

<div id="app">
<div class="container"><form class="form-inline">
<div class="form-group"><label for="exampleInputName2">ID：</label> <input id="exampleInputName2" class="form-control" type="text" /></div>

<button class="btn btn-primary" type="button">提交</button></form>
<table class="table table-hover table-striped">

<tr>
<td>ID</td>
<td>品牌名稱</td>
