How to get query output data

Question

Hi,
I have created procedure to analyze tables. I tried to get output but its not displaye in a proper way. I want to output as like as a query output.
create or replace procedure tablestats
as
begin
for cur in (SELECT OWNER,TABLE_NAME, NUM_ROWS, BLOCKS, AVG_ROW_LEN,TO_CHAR(LAST_ANALYZED, 'MM/DD/YYYY HH24:MI:SS')FROM DBA_TABLES WHERE OWNER='SCOTT') LOOP
dbms_output.put_line(cur.owner||' '||' '||cur.table_name||' '||cur.NUM_ROWS||' '||cur.BLOCKS||' '||cur.AVG_ROW_LEN);
DBMS_STATS.GATHER_TABLE_STATS('scott',cur.table_name);
end loop;
end;
Output came lke this:
SQL> exec tablestats
SCOTT  DEPT 4 4 20
SCOTT  EMP 14 4 38
SCOTT  SALGRADE 5 4 10
SCOTT  SERVICE 8 5 12
SCOTT  BONUS 0 0 0
PL/SQL procedure successfully completed.
Acually i want output like..
  1* SELECT OWNER,TABLE_NAME, NUM_ROWS, BLOCKS, AVG_ROW_LEN,TO_CHAR(LAST_ANALYZED, 'MM/DD/YYYY HH24:MI:SS') Last_Analyzed FROM DBA_TABLES WHERE OWNER=
'SCOTT'
SQL> /
OWNER                          TABLE_NAME                       NUM_ROWS     BLOCKS   AVG_ROW_LEN   LAST_ANALYZED
SCOTT                          DEPT                                             4                   4                 20                   11/27/2013 19:10:44

Hi,
As John said, PL/SQL doesn't give you any of the nice formatting features that front end tools, like SQL*Plus, provide.  If you want headers, you have to say exactly what they are, and write them yourself.  If you want the columns to line up, you have to decide how long they will be and pad them yourself.  It's a lot of work.
Why not let PL/SQL do the things that only PL/SQL can do, and let SQL*Plus do the things it does well?  Have your procedure  or function return a cursor, which you can then diplay in SQL*Plus, or write a piplined function, that you can use in queries where SQL*Plus can format the results.
The query you posted can eaisly be done directly from SQL*Plus, of course.  I assume you posted a very simple example, becuase your question is just about display.  If you don't absolutely need PL/SQL, don't use PL/SQL.  What I said above applies if you really do need PL/SQL.
