Vxe vue vxe-table 分享实现打印表格以及同时打印两张表

vxe-table 默认情况下支持单表打印。
在有些情况下，页面上同时有几张表，这时需要一次性打印出来。可以利用 Vxe 自带的分页打印功能，实现多张表同时打印。

效果

点击打印后自动调起预览，可以直接连接打印机或者导出PDF

代码

实现步骤，
第一步：渲染表格
第二步：通过表格实例的 getPrintHtml() 方法获取打印的 html，不管有几张表都行， 有几张表就调用几次。
第三步：将结构转成分页打印，调用 VxeUI.print 打印

<template>
  <div>
    <vxe-button @click="printEvent">同时打印2张表</vxe-button>

    <vxe-table
      border
      height="300"
      ref="table1Ref"
      :data="tableData1">
      <vxe-column field="id" title="ID" width="60"></vxe-column>
      <vxe-column field="name" title="Name"></vxe-column>
      <vxe-column field="sex" title="Sex"></vxe-column>
      <vxe-column field="address" title="Address"></vxe-column>
    </vxe-table>

    <vxe-table
      border
      height="300"
      ref="table2Ref"
      :data="tableData2">
      <vxe-column field="id" title="ID" width="60"></vxe-column>
      <vxe-column field="role" title="Role"></vxe-column>
      <vxe-column field="age" title="Age"></vxe-column>
    </vxe-table>
  </div>
</template>
