  2. You should call this method by passing your dataset table[0] and name of your data as parameters.
    This method is useful when you export Gridview data to Excel by pass Gridview datasource dataset table[0] as a parameter.

  3. Data from datatable can be imported into excel file with Aspose.Cells for .NET Library also. You can find sample code for this here.
