Can't create comment of a table field with class map

[flyly0755]

Describe the bug
with sql command to creat a table, we can use COMMENT attribute to set a comment for a field.
CREATE TABLE stdfdb.NewTable2
(
Column4 String COMMENT 'TEST',

`Column5` String

)
ENGINE = MergeTree()
ORDER BY Column1
SETTINGS index_granularity = 8192

but with clickhouse-sqlalchemy classs map:
class TbFile(Base, CommonDB2):
tablename = 'tb_file'
table_args = {'comment': 'File Info Table V1.0'}
# id = Column(types.UUID, primary_key=True)
filename = Column(types.String, primary_key=True)
type = Column(types.String, comment='test it')
table_args = (
engines.MergeTree(partition_by='filename', order_by='filename', primary_key='filename'),
)
The comment function not works. after create table with ORM, we can't see the comment 'test it' with the field type
To Reproduce
See above

Expected behavior
Can see the comment 'test it' with the field type

Versions

• clickhouse-sqlalchemy0.1.6
• Python3.8.5
