node mySql 实现数据的导入导出，以及导入批量插入的sql语句-CSDN博客https://blog.csdn.net/snows_l/article/details/139998373

一、效果如图：

二、实现方法

利用里 exceljs 插件的 addImage 方法进行插入， 关键代码如下：

const workbook = new Excel.Workbook();
const worksheet = workbook.addWorksheet('收入明细');
// 设置表头
// worksheet.addRow(['标题', '月份', '收入金额', '备注', '收入截图']);
let baseTableTitle = [{ header: '标题', key: 'title', width: 20 },{ header: '月份', key: 'date', width: 12 },{ header: '收入金额（元）', key: 'money', width: 16 },{ header: '就职于', key: 'source', width: 12 },{ header: '备注', key: 'remark', width: 24 }
];
if (includePic == 'true') {baseTableTitle.push({ header: '收入截图', key: 'pic', width: 16 });
}
worksheet.columns = baseTableTitle;// 循环写入数据
data.forEach(async (item, index) => {const rowData = worksheet.addRow([item.title, item.date, item.money, item.sourceStr, item.remark]);// 指定行高rowData.height = 50;
});// 插入图片
if (includePic == 'true') {for (let i = 0; i < data.length; i++) {// 插入图片到Excelconst imageId = workbook.addImage({filename: '../public' + data[i].pic, // 图片路径 不能出现中文名字extension: 'jpeg'});// E代表第5列，i+2代表第i+2行，F${i+2}:F${i+2}代表第i+2行第6列worksheet.addImage(imageId, `F${i + 2}:F${i + 2}`);}
}// buffer 返回给前端即可
const buffer = await workbook.xlsx.writeBuffer();
