#region 在导出 Excel 前移除 GridView 的各种样式，但是要移除所有相关元素的样式比较繁琐，所以如果想移除所有样式再导出的话可以新建一个包含 GridView(不含任何样式) 的页面，然后绑定需要的数据再用导出

//this.GridView1.HeaderStyle.Reset(); //导出 Excel 前移除 GridView 中 Header 的样式

//this.GridView1.RowStyle.Reset(); //导出 Excel 前移除 GridView 中 Row 的样式

this.GridView1.PagerStyle.Reset(); //导出 Excel 前移除 GridView 中 Pager 的样式

//this.GridView1.ControlStyle.Reset(); //导出 Excel 前移除 GridView 中 Control 的样式 [ 即套用的 GridView 格式 ]
