java poi excel 单元格样式_java poi批量导出excel 设置单元格样式

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

//或者这个方式也可

sheet.setColumnWidth(0, 30 * 256);

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);

//或者这种方式(亲测好使)

//合并addMergedRegion方法四个属性分别是(开始行，结束行，开始列，结束列)

sheet.addMergedRegion(new CellRangeAddress(firstrow, lastrow, firstcol, lastcol));

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);

//如果设置行高

highRow.setHeight((short) (19*20));

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);
