POI命名单元格 - 所有行中的下拉列表都没有所有值

Question

当我使用Apache POI - 使用以下方法命名Cell时创建excel下拉列表时，我遇到了一个奇怪的问题。

public static void createHugeDropDown(XSSFWorkbook wb) {
        int i = 0;
        String sheetName = "LOOKUP";
        String colName = "COL1";
        String mainSheet = "sheet1";
        String[] strArray = new String[]{"10", "20", "30"};
        XSSFSheet sheet = wb.createSheet(sheetName);
        for (String str : strArray) {
            sheet.createRow(i++).createCell(0).setCellValue(str);
        }

        XSSFName namedCell = wb.createName();
        namedCell.setNameName(colName);
        String reference = sheetName + "!A1:A" + i;
        System.out.println(reference);
        namedCell.setRefersToFormula(reference);

        XSSFSheet sheet1 = wb.getSheet(mainSheet);
        int namedCellIndex = wb.getNameIndex(colName);
        namedCell = wb.getNameAt(namedCellIndex);
        AreaReference aref = new AreaReference(namedCell.getRefersToFormula());
        CellReference[] crefs = aref.getAllReferencedCells();
        System.out.println("Total Count --> " + crefs.length);
        for (int count = 0; count < crefs.length; count++) {
            Sheet s = wb.getSheet(crefs[count].getSheetName());
            Row r = sheet.getRow(crefs[count].getRow());
            Cell c = r.getCell(crefs[count].getCol());
            System.out.println("Cell Value" + c.getStringCellValue());
        }

        DataValidationConstraint constraint = null;
        DataValidation dataValidation = null;
        CellRangeAddressList addressList = new CellRangeAddressList(0, 100, 2, 2);
        DataValidationHelper validationHelper = new XSSFDataValidationHelper(sheet1);
        System.out.println(reference);

        constraint = validationHelper.createFormulaListConstraint(reference);
        dataValidation = validationHelper.createValidation(constraint, addressList);
        dataValidation.setSuppressDropDownArrow(true);
        wb.getSheet(mainSheet).addValidationData(dataValidation);
    }

这会让我感到沮丧。但问题是 1）我有10,20＆amp;第一排30 2）有20＆amp;单独在第二排30 3）第三排有30个人。 4）从第四排到第100排空下降。

有人可以在上面的代码中指出我的问题。

我想在所有行的下拉列表中显示所有3个值。
