React使用xlsx和js-export-excel实现前端导出

const dataTable = [
	{index: "1", name: "niko", age: "18", birth: "Mon Dec 11 10:08:15 CST 2023"},
    {index: "1", name: "vivi", age: "16", birth: "Sun Dec 11 10:49:18 CST 2023"},
]

import ExportJsonExcel from 'js-export-excel';

const jsExportExcelHandle = (dataTable = []) => {
	const option = [];
	option.fileName = "个人信息文件";
	const sheetData = dataTable; // 有需要映射的话需要先映射
	const sheetFilter = ["index", "name", "age"];
	const sheetHeader = ["序号", "姓名", "年龄"];
	option.datas = [
		{
			sheetData,
			sheetName: "个人信息表",
			sheetFilter,
			sheetHeader,
			columnWidth: new Array(sheethaeader.length).fill(10); // 列宽
		}
	];
	const toExcel = new ExportJsonExcel(option);
	toExcel.saveExcel()
}

import { utils, writeFile } from 'xlsx';

const xlsxHandle = (dataTable = []) => {
	// 表头映射为中文
	const headerMap = {
		index: "序号",
		name: "姓名",
		age: "年龄",
	},
	// 先过滤出需要的属性
	const headList = Object.keys(headerMap); 
	// 返回新的对象数组
	const _dataTable = dataTable.map(item => {
		const filteredItem = {};
		Object.keys(item).forEach(key => {
			if(headList.includes(key)){
				filteredItem[key] = item[key];
			}
		})
        return filteredItem
	})
    
    // xlsx需要转为二维数组
    const dataArr = _dataTable.map(item => Object.values(item));
    // 将表头映射为中文（name => 姓名）
    const headerTranslated = Object.keys(headerMap).map(key => header[key]);//["序号", "年龄", "姓名"]
    dataArr.unshif(headerTranslated); // 插入
    const workSheet = utils.aoa_to_sheet(dataArr); // 转为工作表对象
    // 设置每个的单元格的列宽
    workSheet["!cols"] = new Array(headList.length).fill({wch: 20}); // {!cols:(13)[{wch:20},...],A1:{v: "序号", t: "s"},...} 
    const workBook = utils.book_new();
    utils.book_append_sheet(workBook, workSheet);
    // writeFile 方法只能在 node 环境下使用。
    writeFile(workBook, "个人信息文件.xlsx", {
        Props: { // 作者的相关信息
            title: "个人信息明细",
            creator: window.User,
         
        }
    })
}

//wpx 字段表示以像素为单位，wch 字段表示以字符为单位
worksheet['!cols'] = [
  { wpx: 200 }, //设置第1列列宽为200像素
  { wch: 50 },  //设置第2列列宽为50字符
];

//设置A1单元格的值是序号，类型是字符串，字体颜色是FF0187FA
worksheet["A1"] = {
    v: "序号",
    t: "s",
    s: {
        font: {
            color: { rgb: "FF0187FA" }
        },
    }
}

// 应该根据表头headerMap重新组装每一行的对象
const dataArr = _dataTable.map(item => 
    Object.keys(headerMap)
    .map(key => item[key])
)
