POI 3.17 导出样式（边框&居右）

3.17跟之前的版本很多样式都不一样，好多不可以用，百度了一圈愣是没找到；都不适用

// 创建
HSSFCellStyle style = workbook.createCellStyle();

// 样式设置

style.setBorderBottom(BorderStyle.THIN);//下边框  
style.setBorderLeft(BorderStyle.THIN);//左边框  
style.setBorderRight(BorderStyle.THIN);//右边框  
style.setBorderTop(BorderStyle.THIN);//上边框
style.setAlignment(HorizontalAlignment.CENTER);// 居中

style.setAlignment(HorizontalAlignment.RIGHT);// 居右

style.setAlignment(HorizontalAlignment.LEFT);// 居左
