把GridView1的数据导出到excel的sheet1把GridView2的数据导出到excel的sheet2.

Posted 2023-03-30

情况是这个样子的：
在一个页面里有俩个GridView，有一个导出按钮，点击导出按钮的时候，把GridView1的内容导出到excel的sheet1里，
把GridView2的内容导出到excel的sheet2里。
大家帮帮忙吧，谢谢。

另外还有几个小问题：
1.导出的时候怎么在excel中插入一行，就是想写个表头，表头的字自己写。（用代码实现）
2.excel的sheet1的名字怎么改掉？（用代码实现）
谢谢大家了。能帮一个就帮一个吧。
