                application.DefaultVersion = ExcelVersion.Excel2016;
 
                IWorkbook workbook = application.Workbooks.Open("../../Data/Sample.xlsx");
                IWorksheet worksheet = workbook.Worksheets[0];
 
                IListObject table = worksheet.ListObjects[0];
 
                table.Columns[1].Name = "NewName";
 
                workbook.SaveAs("Output.xlsx");
                System.Diagnostics.Process.Start("Output.xlsx");
