> Currently the fields in table magic are sorted by field name by default, but in many scenarios, we want to keep fields of table magic in query order, for example:
> {code:scala}
> val result = spark.sql("select b, a from table")
> %table result
> {code}
> currently Livy responses json with fields in the order of "a", "b", but we want them in the order of "b", "a" which is consistent with the SQL
