1. 效果图

2. 步骤

2.1. 安装插件

• vue3版本 文档地址

npm install vue3-print-nb --save

• vue2版本 文档上同

npm install vue-print-nb --save

2.2. 注册组件 - 以Vue3为例

• 全局注册 - main.js

import print from 'vue3-print-nb'
const app = createApp(App)
app.use(print)

• 按需注册

<script setup>
import vPrint from 'vue3-print-nb'
</script>

2.3. 代码展示

<template>
  <div id="main">
    <el-table
      :data="tableData"
      :span-method="arraySpanMethod"
      border
      style="width: 100%"
    >
      <el-table-column prop="id" label="ID" width="180" />
      <el-table-column prop="name" label="Name" />
      <el-table-column prop="amount1" sortable label="Amount 1" />
      <el-table-column prop="amount2" sortable label="Amount 2" />
      <el-table-column prop="amount3" sortable label="Amount 3" />
    </el-table>

    <el-table
      :data="tableData"
      :span-method="objectSpanMethod"
      border
      style="width: 100%; margin-top: 20px"
    >
      <el-table-column prop="id" label="ID" width="180" />
      <el-table-column prop="name" label="Name" />
      <el-table-column prop="amount1" label="Amount 1" />
      <el-table-column prop="amount2" label="Amount 2" />
      <el-table-column prop="amount3" label="Amount 3" />
    </el-table>
  </div>

  <el-button type="primary" v-print="{ id: '#main', popTitle: '打印标题标题' }"
    >打印页面</el-button
  > // 重点代码1
</template>

<script setup>
import vPrint from 'vue3-print-nb'; // 重点代码2

const arraySpanMethod = ({ row, column, rowIndex, columnIndex }) => {
  if (rowIndex % 2 === 0) {
    if (columnIndex === 0) {
      return [1, 2];
    } else if (columnIndex === 1) {
      return [0, 0];
    }
  }
};

const objectSpanMethod = ({ row, column, rowIndex, columnIndex }) => {
  if (columnIndex === 0) {
    if (rowIndex % 2 === 0) {
      return {
        rowspan: 2,
        colspan: 1,
      };
    } else {
      return {
        rowspan: 0,
        colspan: 0,
      };
    }
  }
};

const tableData = [
  {
    id: '12987122',
    name: 'Tom',
    amount1: '234',
    amount2: '3.2',
    amount3: 10,
  },
  {
    id: '12987123',
    name: 'Tom',
    amount1: '165',
    amount2: '4.43',
    amount3: 12,
  },
  {
    id: '12987124',
    name: 'Tom',
    amount1: '324',
    amount2: '1.9',
    amount3: 9,
  },
  {
    id: '12987125',
    name: 'Tom',
    amount1: '621',
    amount2: '2.2',
    amount3: 17,
  },
  {
    id: '12987126',
    name: 'Tom',
    amount1: '539',
    amount2: '4.1',
    amount3: 15,
  },
];
</script>

<style lang="scss" scoped></style>

注意：该插件有非常多的api，通过v-print以object形式交互，官网api参考如下:

<el-button v-print="printObj" class="mt-lg" type="primary">打印成PDF观看</el-button>
<div id="print">需要打印的内容</div>
const printObj = {
  id: '#print',
};
