向Excel中追加数据

读取Excel模版插入数据并生成一个新的文件保存

本文中接受03的excel操作（跟07一样不过 其中的  HSSF  换成 XSSF）

FileInputStream fileInputStream = new FileInputStream(templeExcelPath);
            HSSFWorkbook xssfWorkbook = new HSSFWorkbook(fileInputStream);
            HSSFSheet xssfSheet = xssfWorkbook.getSheetAt(0);
HSSFRow xssfRow = xssfSheet.createRow(xssfSheet.getLastRowNum() + 1);
        xssfRow.createCell(0).setCellValue(type);//插入类型
        xssfRow.createCell(1).setCellValue(title);//插入题干
        xssfRow.createCell(2).setCellValue(option);//插入选项
        xssfRow.createCell(3).setCellValue(answer);//插入答案
        xssfRow.createCell(4).setCellValue(remark);//插入讲解
        xssfRow.createCell(5).setCellValue(complexity);//插入难度
        xssfRow.createCell(6).setCellValue(score);//插入分数
        HSSFCellStyle cellStyle = xssfWorkbook.createCellStyle();
        HSSFFont font = xssfWorkbook.createFont();
        font.setFontHeightInPoints((short) 11);
        cellStyle.setFont(font);
        cellStyle.setAlignment(HSSFCellStyle.ALIGN_JUSTIFY);
        cellStyle.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);
setCellStyle(cellStyle, xssfRow);
 FileOutputStream os = new FileOutputStream(exportExcelPath + fileName+".xls");
            xssfWorkbook.write(os);
            fileInputStream.close();
            os.close();

    public static void setCellStyle(HSSFCellStyle cellStyle, HSSFRow row) {
        for (int i = 0; i < row.getLastCellNum(); i++) {
            Cell cell = row.getCell(i);
            cell.setCellStyle(cellStyle);
        }
    }
