適用条件
elementuiを使用したネイティブタブまたはテーブルコンポーネントは、基本テーブルまたは結合されたセルの場合にエクスポートできます。
短所: エクスポートされた Excel はページテーブルのスタイルと互換性がなく、フリーズ機能と互換性がありません。スタイルを制御する必要がある場合は、パブリックメソッドのコードを通じて追加されたスタイルを判断する必要があります
1. 次のプラグインをインストールします。バージョンが異なるとエラー レポートが異なる場合があることに注意してください。インストールするには、次のバージョンをロックすることをお勧めします。
"xlsx": "^0.17.4"、
"xlsx-style": "^0.8.13"
"file-saver": "^2.0.5"
注: インストールが成功すると、スタートアップ プロジェクトはエラーを報告します。
解決策:
(1).node_modules->xlsx-style->dist->cpexcel.js の 807 行目の内容を次の内容に置き換える必要があります。そうしないと、cpexcel.js ファイルが見つからないというエラーが報告されます。 var
cpt = require('. /cpt' + 'able'); var cpt = './cptable';
(2) に変更し、vue.config.js で次の設定を行います。方法 2 を使用することをお勧めします。この方法は開発環境にとって非常に重要であり、パッケージ化されたデプロイメントは有効です。
module.exports = {
chainWebpack: config => {
config.externals({
'./cptable': 'var cptable' })
}
}
2. ファイル xlsxStyle.utils.js をインポートします。

3. エクスポートされたパブリックメソッドファイル
import FileSaver from 'file-saver'
import XLSX from 'xlsx'
import xlsxStyle from 'xlsx-style'
import XSU from './../assets/js/xlsxStyle.utils'
// 表格导出成excel
export const exportFile = (dom, name, date) => {
// dom: 目标div的id，如document.querySelector('#tableToExcel')
// name: 自定义导出excel的名称
// date: 追加日期

let fileName = name
let fix = document.querySelector('.el-table__fixed');
let wb

4.使用する
使用する必要がある vue ファイルでは、
import {
exportFile } from '@/utils/util'// 路径为exportFile方法所在的js文件的路径
exportFile(document.querySelector('#tableToExcelDaily'),'能源指标日报',`${
state.dateRange[0]}-${
state.dateRange[1]}`);
