//Create a workbook with a worksheet
IWorkbook workbook = excelEngine.Excel.Workbooks.Create(1);
//Access first worksheet from the workbook instance
IWorksheet worksheet = workbook.Worksheets[0];
worksheet.Range["C6"].HorizontalAlignment = ExcelHAlign.HAlignCenter;
worksheet.Range["C6"].Text = "Merging the cells in XlsIO";
