assert result_ext_table == expected_ext_table`

To Reproduce
Steps to reproduce the behavior:
run the test

Expected behavior
a success

Additional context
the file format STRIP_OUTER_ARRAY trigger the def tokens_not_columns_names(self, t: LexToken) -> LexToken: t_tag = self.parse_tags_symbols(t) if t_tag: return t_tag if "ARRAY" in t.value : t.type = "ARRAY" return t the if ARRAY statement it should not, adding a len<15 could solve the problem
