String 神谕如何将包含描述coulmns的表格式化为spool输出？

第一个表没有任何长字符串，并且输出格式良好：

SQL> select * from Visit;

       SLOTNUM DATEVISIT ACTUALARR                                                                                     
    ---------- --------- ---------                                                                                     
            12 19-JUN-13 19-JUN-13                                                                                     
            15 20-JUN-13 20-JUN-13                                                                                     
            18 21-JUN-13 21-JUN-13                                                                                     

然而，第二个表包含

Description

列，并且输出是一个完全混乱的

SQL> select * from Treatment;

        TREATC NAME
