POI 設置Excel樣式

POI中可能會用到一些須要設置EXCEL單元格格式的操做小結：

先獲取工做薄對象:

HSSFWorkbook wb = new HSSFWorkbook();

HSSFSheet sheet = wb.createSheet();

HSSFCellStyle setBorder = wb.createCellStyle();

1、設置背景色：

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

2、設置邊框:

setBorder.setBorderBottom(HSSFCellStyle.BORDER_THIN); //下邊框
setBorder.setBorderLeft(HSSFCellStyle.BORDER_THIN);//左邊框
setBorder.setBorderTop(HSSFCellStyle.BORDER_THIN);//上邊框
setBorder.setBorderRight(HSSFCellStyle.BORDER_THIN);//右邊框

3、設置居中:

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

setBorder.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER); // 上下居中

4、設置字體:

HSSFFont font = wb.createFont();
font.setFontName("黑體");
font.setFontHeightInPoints((short) 16);//設置字體大小

HSSFFont font2 = wb.createFont();
font2.setFontName("仿宋_GB2312");
font2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//粗體顯示
font2.setFontHeightInPoints((short) 12);

setBorder.setFont(font);//選擇須要用到的字體格式

5、設置列寬:

sheet.setColumnWidth(0, 3766); //第一個參數表明列id(從0開始),第2個參數表明寬度值

6、設置自動換行:

setBorder.setWrapText(true);//設置自動換行

7、合併單元格:

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

//參數1：起始行號       參數2：終止行號       參數3：起始列號             參數4：終止列號
sheet.addMergedRegion(region1);

8、加邊框

  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);
