- Check the Dflag variable inside of function dump_table to see if data should be
dumped or not.
    - Add test for --xml and --no-data as well
    Reapplying patch!

  Move the check of --no-data flag and "number of fields" inside of the dump_table
  function.

  Update test results add ouput for --xml and --no-data
