--我的表中有一些行，我想以 excel 格式导出。这一步相当于用户输入搜索条件，所有匹配的行都会导出到一个excel文件中。
--用户对excel文件进行修改。添加或更新行。
--用户上传文件，所有更新的行都更新到数据库中，所有添加的行都添加到数据库中。
我想在 PHP 中做的所有这些事情，它使用的数据库是 MySQL。服务器正在运行 Linux（没有 COM！）
我已经分别完成了上面解释的导出和导入部分。
我正在使用PHPExcelReader 读取文件并保存它。但这需要用户先下载模板，从导出的excel中复制数据并粘贴到模板中。
为了导出，我只是创建了一个简单的 HTML 表格并欺骗了浏览器，它是一个 excel！ Excel 将打开 HTML 表格，但当然在保存该文件时，它会更改格式并使其成为有效的 Excel 文件。
请就如何使其发挥作用提出一些想法？ ：/
谢谢...非常感谢您的帮助。
