Vue.js bootstrap前端实现分页和排序

<td >{{dataItem.id}}</td>
<input v-model="message">

<th v-on:click="sortBy('id')">ID</th>

<option v-for="item in arrPageSize" value="{{item}}">{{item}}</option>

//定义
Vue.filter( 'name' , function(value) {
  return value * .5 ;
 });
//使用
<td>{{dataItem.age | name}}</td>
