IWorksheet worksheet = workbook.getWorksheets().get(0);
worksheet.getRange("B:F").setColumnWidth(20);
worksheet.getRange("4:7").setRowHeight(60);
worksheet.getRange("A:A").setColumnWidth(5);
worksheet.getRange("B2").setValue("Code128");
worksheet.getRange("B2:F2").setMergeCells(true);
worksheet.getRange("B3:F3")
        .setValue(new Object[][] { { "Name", "Number", "Default", "Hidden Label", "Custom Label Font" } });
worksheet.getRange("B4:C7").setHorizontalAlignment(HorizontalAlignment.Center);
worksheet.getRange("B4:C7").setVerticalAlignment(VerticalAlignment.Center);

        .setValue(new Object[][] { { "Police", 911 }, { "Telephone Directory Assistance", 411 },
                { "Non-emergency Municipal Services", 311 }, { "Travel Info Call 511", 511 } });
worksheet.getRange("B4:C6").setWrapText(true);
worksheet.getRange("G6").setWrapText(true);
worksheet.getPageSetup().setOrientation(PageOrientation.Landscape);
worksheet.getPageSetup().setPrintGridlines(true);
// Set formula
for (int i = 4; i < 8; i++) {
    worksheet.getRange("D" + i).setFormula("=BC_CODE128" + "(C" + i + ")");
    worksheet.getRange("E" + i).setFormula("=BC_CODE128" + "(C" + i + ", , , false))");
    worksheet.getRange("F" + i)
            .setFormula("=BC_CODE128" + "(C" + i + ", , , true, \"top\", \"B\",\"Arial\", \"normal\")");
}

// Save to an pdf file
