POI中可能会用到一些需要设�|�EXCEL单元格格式的操作��结�Q?br />
先获取工作薄对象:

HSSFWorkbook wb = new HSSFWorkbook();

HSSFSheet sheet = wb.createSheet();

HSSFCellStyle setBorder = wb.createCellStyle();

一、设�|�背景色�Q?br />
setBorder.setFillForegroundColor((short) 13);// 讄��背景�?br />
setBorder.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

二、设�|�边�?

setBorder.setBorderBottom(HSSFCellStyle.BORDER_THIN); //下边�?br />
setBorder.setBorderLeft(HSSFCellStyle.BORDER_THIN);//左边�?br />
setBorder.setBorderTop(HSSFCellStyle.BORDER_THIN);//上边�?br />
setBorder.setBorderRight(HSSFCellStyle.BORDER_THIN);//双��?br />
三、设�|�居�?

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

四、设�|�字�?

HSSFFont font = wb.createFont();

font.setFontName("黑体");

font.setFontHeightInPoints((short) 16);//讄��字体大小

HSSFFont font2 = wb.createFont();

font2.setFontName("仿宋_GB2312");

font2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//�_�体昄��

font2.setFontHeightInPoints((short) 12);

setBorder.setFont(font);//选择需要用到的字体格式

五、设�|�列�?

sheet.setColumnWidth(0, 3766); //�W�一个参��C��表列id(�?开�?,�W?个参��C��表宽度�?br />
六、设�|�自动换�?

setBorder.setWrapText(true);//讄��自动换行

七、合�q�单元格:

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

//参数1�Q�行�?参数2�Q��v始列�?参数3�Q�行�?参数4�Q�终止列�?br />
sheet.addMergedRegion(region1);
