Mainly use the template tag, which can be equivalent to php foreach()

 foreach（lists as $key）{
 //todo
  foreach($key.Custom fields as k){
  //todo
  }
 }

&lt;template v-for="key in lists" v-cloak&gt;
  &lt;tr&gt;
   &lt;td&gt;&lt;/td&gt;
   &lt;td &gt;&lt;/td&gt;
   &lt;td &gt;&lt;/td&gt;
   &lt;td &gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr v-for="v in key.custom fields"&gt;
   &lt;td&gt;&lt;/td&gt;
   &lt;td v-text=""&gt;&lt;/td&gt;
   &lt;td v-text=""&gt;&lt;/td&gt;
   &lt;td v-text=""&gt;&lt;/td&gt;
  &lt;/tr&gt;
&lt;/template&gt;
