工作薄中不同类型的单元格
[java]
Workbook wb = new HSSFWorkbook(); 
 Sheet sheet = wb.createSheet("new sheet"); 
 Row row = sheet.createRow(2); 
 row.createCell(0).setCellValue(1.1);//浮点  
 row.createCell(1).setCellValue(new Date());//日期  
 row.createCell(2).setCellValue(Calendar.getInstance());//日期  
 row.createCell(3).setCellValue("a string");//字符串  
 row.createCell(4).setCellValue(true);//Boolean  
 row.createCell(5).setCellType(Cell.CELL_TYPE_ERROR);//错误  
 
 // 写入文件  
 FileOutputStream fileOut = new FileOutputStream("workbook.xls"); 
 wb.write(fileOut); 
 fileOut.close(); 

   Workbook wb = new HSSFWorkbook();
    Sheet sheet = wb.createSheet("new sheet");
    Row row = sheet.createRow(2);
    row.createCell(0).setCellValue(1.1);//浮点
