poi设置excel的预选下拉框

 同一个excel下可以多列使用

public void setExcelComboBox(HSSFWorkbook workbook, HSSFSheet sheet, String[] data, String hiddenName, int firstRow, int lastRow, int firstCol, int lastCol) {
        HSSFSheet hidden = workbook.createSheet(hiddenName);
        HSSFCell cell = null;
        for (int i = 0; i < data.length; i++) {
            String name = data[i];
            HSSFRow row = hidden.createRow(i);
            cell = row.createCell(0);
            cell.setCellValue(name);
        }

        Name namedCell = workbook.createName();
        namedCell.setNameName(hiddenName);
        namedCell.setRefersToFormula(hiddenName+"!$A$1:$A$" + data.length);
        //加载数据,将名称为hidden的
        DVConstraint constraint = DVConstraint.createFormulaListConstraint(hiddenName);

        // 设置数据有效性加载在哪个单元格上,四个参数分别是：起始行、终止行、起始列、终止列
        CellRangeAddressList addressList = new CellRangeAddressList(firstRow, lastRow, firstCol, lastCol);
        DataValidation validation = new HSSFDataValidation(addressList, constraint);

        //将第二个sheet设置为隐藏
        workbook.setSheetHidden(1, true);

        sheet.addValidationData(validation);
    }
