POI HSSFCellStyle 设置 Excel 单元格样式

POI中可能会用到一些需要设置EXCEL单元格格式的操作小结：

先获取工作薄对象:

HSSFWorkbook wb = new HSSFWorkbook();

HSSFSheet sheet = wb.createSheet();

HSSFCellStyle setBorder = wb.createCellStyle();

一、设置背景色：

setBorder.setFillForegroundColor((short) 13);// 设置背景色
setBorder.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

二、设置边框:

setBorder.setBorderBottom(HSSFCellStyle.BORDER_THIN); //下边框
setBorder.setBorderLeft(HSSFCellStyle.BORDER_THIN);//左边框
setBorder.setBorderTop(HSSFCellStyle.BORDER_THIN);//上边框
setBorder.setBorderRight(HSSFCellStyle.BORDER_THIN);//右边框

三、设置居中:

setBorder.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 居中

四、设置字体:

HSSFFont font = wb.createFont();
font.setFontName("黑体");
font.setFontHeightInPoints((short) 16);//设置字体大小

HSSFFont font2 = wb.createFont();
font2.setFontName("仿宋_GB2312");
font2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//粗体显示
font2.setFontHeightInPoints((short) 12);

setBorder.setFont(font);//选择需要用到的字体格式

五、设置列宽:

sheet.setColumnWidth(0, 3766); //第一个参数代表列id(从0开始),第2个参数代表宽度值

六、设置自动换行:

setBorder.setWrapText(true);//设置自动换行

七、合并单元格:

Region region1 = new Region(0, (short) 0, 0, (short) 6);

//参数1：行号 参数2：起始列号 参数3：行号 参数4：终止列号
sheet.addMergedRegion(region1);

八、加边框

  HSSFCellStyle cellStyle= wookBook.createCellStyle();
  cellStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);
  cellStyle.setBorderBottom(HSSFCellStyle.BorderBORDER_MEDIUM);
  cellStyle.setBottomBorderColor(HSSFColor.BLACK.index);
  cellStyle.setBorderLeft(HSSFCellStyle.BORDER_MEDIUM);
  cellStyle.setLeftBorderColor(HSSFColor.BLACK.index);
  cellStyle.setBorderRight(HSSFCellStyle.BORDER_MEDIUM);
  cellStyle.setRightBorderColor(HSSFColor.BLACK.index);
  cellStyle.setBorderTop(HSSFCellStyle.BORDER_MEDIUM);
  cellStyle.setTopBorderColor(HSSFColor.BLACK.index);

例子：

@ResponseBody

    @RequestMapping(value = "/reportForms/joinStocktaking/exportStorage.api")

    public AjaxResponse exportStorage(@RequestBody StorageModel model) throws Exception { 

        if (logger.isDebugEnabled())

            logger.debug("tmpdir is, {}", System.getProperty(JAVA_IO_TMPDIR));

        int row = 1;

        HSSFWorkbook workbook = new HSSFWorkbook();

        HSSFSheet hssfSheet = workbook.createSheet();

        HSSFCellStyle style = workbook.createCellStyle();

        style.setFillBackgroundColor(HSSFCellStyle.LEAST_DOTS);

        style.setFillPattern(HSSFCellStyle.LEAST_DOTS);

        //设置Excel中的边框(表头的边框)

        style.setAlignment(HSSFCellStyle.ALIGN_CENTER);

        style.setBorderBottom(HSSFCellStyle.BORDER_MEDIUM);

        style.setBottomBorderColor(HSSFColor.BLACK.index);

        style.setBorderLeft(HSSFCellStyle.BORDER_MEDIUM);

        style.setLeftBorderColor(HSSFColor.BLACK.index);

        style.setBorderRight(HSSFCellStyle.BORDER_MEDIUM);

        style.setRightBorderColor(HSSFColor.BLACK.index);

        style.setBorderTop(HSSFCellStyle.BORDER_MEDIUM);

        style.setTopBorderColor(HSSFColor.BLACK.index);

        //设置字体

        HSSFFont font = workbook.createFont();

        font.setFontHeightInPoints((short) 14); // 字体高度

        font.setFontName(" 黑体 "); // 字体

        style.setFont(font);

        HSSFRow firstRow = hssfSheet.createRow((short) 0);

        HSSFCell firstCell = firstRow.createCell(0);

        firstRow.setHeight((short) 400);

        //设置Excel中的背景

        style.setFillForegroundColor(HSSFColor.GREEN.index);

        style.setFillBackgroundColor(HSSFColor.GREEN.index);

        firstCell.setCellValue(new HSSFRichTextString("库房"));

        firstCell.setCellStyle(style);

        HSSFCell secondCell = firstRow.createCell(1);

        firstRow.setHeight((short) 400);

        style.setFillForegroundColor(HSSFColor.GREEN.index);

        style.setFillBackgroundColor(HSSFColor.GREEN.index);

        style.setFillBackgroundColor(HSSFColor.GREEN.index);

        fiveCell.setCellValue(new HSSFRichTextString("在库数量"));

        fiveCell.setCellStyle(style);

        HSSFCell sixCell = firstRow.createCell(5);

        firstRow.setHeight((short) 400);

        style.setFillBackgroundColor(HSSFColor.GREEN.index);

        sixCell.setCellValue(new HSSFRichTextString("锁定数量"));

        sixCell.setCellStyle(style);

        //设置列宽

        hssfSheet.setColumnWidth(0, 7000);

        hssfSheet.setColumnWidth(1, 8000);

        hssfSheet.setColumnWidth(2, 4000);
