vue.js 双层嵌套for遍历的方法详解, 类似php foreach()

 foreach（lists as $key）{
 //todo
  foreach($key.自定义字段 as k){
  //todo
  }
 }

<template v-for="key in lists" v-cloak>
  <tr>
   <td></td>
   <td ></td>
   <td ></td>
   <td ></td>
  </tr>
  <tr v-for="v in key.自定义字段">
   <td></td>
   <td v-text=""></td>
   <td v-text=""></td>
   <td v-text=""></td>
  </tr>
</template>
