While openreport is a very viable solution.  Here are my thoughts for whatever 
it is worth.

See my recent post to another Table issue.  However it is relevant I think.  
You need to use multiple tables in your case.  You could use spanning, but I 
think that is more complex for this case and is not needed.  So just append 
each table one after the other.

# BEGIN T1
NAME         -- ID       -- DATE
--------------------------------------
KERRY, JOHN  -- ID 12345 -- 2004/12/12 
# END T1
# BEGIN T2
   ID -- TITLE
    ---------------------------
    1  -- HELLO AMERICA 1
    2  -- HELLO AMERICA 2
# END T2
# Spacer flowable or other flowable
# REPEAT T1 with different data
BUSH, GEORGE -- ID 12346 -- 2004/12/11
# END REPEAT T1
# BEGIN REPEAT T2 with different data
    ---------------------------
    1  -- MASSIVE DESTRUCTION 1
    2  -- TERRORISM 2
# END REPEAT T2
# AND SO ON

so if story was our array to pass the build method.
story.append(T1)
story.append(T2)
story.append(T1-diff_data)
story.append(T2-diff_data)
