POI操作Excel换行

网上很多博客操作Excel换行的都是Office2007之前的格式，一直没找到支持扩展名为.xlsx的换行方式，被折腾到要死，无奈之下只能去官网看看，发现了同时支持.xlsx和.xls两种扩展的。现在列出如下：

  Workbook wb = new XSSFWorkbook();   //or new HSSFWorkbook();  Sheet sheet = wb.createSheet();  Row row = sheet.createRow(2);  Cell cell = row.createCell(2);  cell.setCellValue("Use \n with word wrap on to create a new line");   //to enable newlines you need set a cell styles with wrap=true  CellStyle cs = wb.createCellStyle();  cs.setWrapText(true);  cell.setCellStyle(cs);  //increase row height to accomodate two lines of text  row.setHeightInPoints((2*sheet.getDefaultRowHeightInPoints()));  //adjust column width to fit the content  sheet.autoSizeColumn((short)2);  FileOutputStream fileOut = new FileOutputStream("ooxml-newlines.xlsx");  wb.write(fileOut);  fileOut.close();
