POI-HSSFWorkbook合并单元格及文字居中问题

// 合并单元格：参数：起始行, 终止行, 起始列, 终止列
CellRangeAddress cra = new CellRangeAddress(rowIndex, rowIndex, 0, k);
sheet.addMergedRegion(cra);
//注意：边框样式需要重新设置一下
RegionUtil.setBorderTop(HSSFBorderFormatting.BORDER_THICK, cra, sheet, wb);
//合并的单元格样式
HSSFCellStyle boderStyle = wb.createCellStyle();
//垂直居中
boderStyle.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);
//水平居中
boderStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);
