本文詳細解答了如何使用Aspose.Cells導出DataGrid數據到Excel的方法。

	 '導出數據到EXCEL文件

	    '---------------------------------------------------------------------------------------

	    '說明：只能導出一個DATAGRID，并將DATAGRID中顯示的數據保存到EXCEL中

	    '    DATAGRID只能而且必須存在一個TableStyle，且必須包含可以顯示的列

	    '參數：     dg：需要導出的DATAGRID實例

	    '           RowCount：需要導出的行數

	    '           SheetName：EXCEL中Sheet的名稱

	    '           FilePath：文件保存的全路徑名

	    '           IsChar：是否設置成字符格式

	    '返回：     導出結果
