specifications:[ {  specificationName:"颜色",  specificationItem:[   {value:"黄色"},   {value:"黑色"}   ] }]

<table class="table table-bordered table-hover table-item spggdytable"  id="ggxtable" v-show="isAddSpecifications"> <thead> <tr>  <th>排序</th>  <th>规格项</th>  <th>操作</th> </tr> </thead> <tbody> <tr v-for="(item,index) in specifications">  <td>{{index}}</td>  <td>{{item.specificationName}}</td>  <td>   <a href='#'> <img src='../img/common_edit@25.png' alt='修改'></a>   <a href='#'><img src='../img/common_del@25.png' alt='删除'></a>  </td> </tr> </tbody></table><table class="table table-bordered table-hover table-item spggdytable"  id="ggztable" v-show="isAddSpecifications"> <thead> <tr>  <th>规格值</th>  <th>操作</th> </tr> </thead> <tbody v-for="(item,index) in specifications"> <tr v-for="(part,n) in item.specificationItem">  <td>{{part.value}}</td>  <td>   <a href='#'> <img src='../img/common_edit@25.png' alt='修改'></a>   <a href='#'><img src='../img/common_del@25.png' alt='删除'></a>  </td> </tr> </tbody></table>
