import Print from 'vue-print-nb'　　Vue.use(Print); //注册

<div id="printTest" >

　　   <p>明月照于山间</p>

　　　　<p>清风来于江上 </p>

</div>

<button v-print="'#printTest'">打印</button>

import Print from '@/plugs/print'
Vue.use(Print) // 注册
<template>
　　<section ref="print">
　　　　打印内容
　　　　<div class="no-print">不要打印我</div>
　　</section>
</template>
this.$print(this.$refs.print) // 使用

<div class="no-print">不要打印我</div>

<div class="do-not-print-me-xxx">不要打印我</div>this.$print(this.$refs.print,{'no-print':'.do-not-print-me-xxx'}) // 使用

<template>
    <div>
        <ul class="print-ul">
            <li v-for="(item,index) of tableData" :key="index"
