导出excel修改样式

protected HSSFWorkbook workbook = null;
protected HSSFSheet curSheet = null;
protected HSSFRow curRow = null;
protected HSSFCellStyle curStyle = null;

excel合并单元格
//合并第r行的，从第2列开始，第三列结束，相当于合并第r行的第2列与第三列
this.curSheet.addMergedRegion( new Region( r, ( short )1, r, ( short )3 ) );

//合并第1列的，从第r行合并到第r+5行
this.curSheet.addMergedRegion( new Region( r, ( short )0, r + 5, ( short )0 ) );

//修改样式
//修改excel下边框大小为0
this.curStyle.setBorderBottom((short)0);
//修改excel左边框大小为0
this.curStyle.setBorderLeft((short)0);

//单元格内容换行

强制换行 直接加"\n"
HSSFCellStyle style = workbook.createCellStyle();
style.setWrapText(true);//自动换行



//10号字体，带边框，垂直居中
