使用xlsx插件把table转成excel文件并下载

安装xlsx插件

npm i xlsx -S

使用

import XLSX from "xlsx"

export const exportExcel = (tableName, excelName) => {
    const wb = XLSX.utils.table_to_book(document.querySelector(`#${tableName}`), {
        raw: true  // 使用原始字符串（例如不想对"%"进行转换时使用）
    });
    /* 获取二进制字符串作为输出 */
    const wbout = XLSX.write(wb, {
        bookType: "xlsx",
        bookSST: true,
        type: "array"
    });
    downloadExcel(wbout, excelName);
}

/**
 * 下载Excel文件流
 * @param {string} binaryData 
 * @param {string} fileName 
 */
export const downloadExcel = (binaryData, fileName) => {
    const a = document.createElement("a");
    a.download = fileName;
    a.style.display = "none";
    a.href = URL.createObjectURL(new Blob([binaryData], { type: 'application/vnd.ms-excel' }));
    document.body.appendChild(a);
    a.click();
    URL.revokeObjectURL(a.href);
    document.body.removeChild(a);
}
