POI中可能会使用到少量需要设置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);//选择需要使用到的字体格式

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);
