docstring: What this method does is set the column so that if the same data appears in
  consecutive rows, then it is not repeated.
  
  For example, in the quiz overview report, the fullname column is set to be suppressed, so
  that when one student has made multiple attempts, their name is only printed in the row
  for their first attempt.
  @param int $column the index of a column.
