        Workbook workbook = new Workbook();
        workbook.loadFromFile("sample.xlsx");

        //Get the first worksheet.
        Worksheet worksheet = workbook.getWorksheets().get(0);

        //Set the height of the third row to 25
        worksheet.setRowHeight(3,25);

        //Set the width of the second column to 20
        worksheet.setColumnWidth(2, 20);
