Modify output of a query

-- The code below works.

declare
     v_row  integer := 0;
     v_rowcnt integer;
 begin
     for t in (select table_name from user_tables order by 1) loop
         v_row := v_row + 1;
         execute immediate 'select count(*) from ' || t.table_name into v_rowcnt;
         dbms_output.put_line (rpad(v_row, 5, ' ') || (rpad(t.table_name,40,'.') || v_rowcnt));
     end loop;    
 end;

I want to add the corresponding Tablespace_Name to the output for it to look like

1    ACCOUNT................................23..............Adv_Data                
2    AD......................................       50..............Adv_Data          
3    AD_AGE_STATED...................70.............Adv_Data
4    AD_BODY.................................60............ Bev_Data
5    AD_CATEGORY......................45..............Adv_Data          
6    AD_LOCATION_STATED.......25..............Bev_Data

What change to make in the code on top.
