Review Comment: I'm thinking the behavior here could be a bit misleading, given the variant `DataType::Table`, the expectation is that `self.parse_data_type()` can parse that variant. Would that be reasonable to do here instead (i.e. the table type logic is moved into `parse_data_type()` and this part becomes unchanged [likely no need to guard by dialect either since the syntax doesn't conflict] I imagine as a result)? -- This is an automated message from the Apache Git Service.
