Yubin Li commented on FLINK-29679:
----------------------------------

[~luoyuxia] table's comment is a table level prop, we could use `show create table <table_name>` to display table's comment, eg:

```

CREATE TABLE `default_catalog`.`default_database`.`t2` (
  `id` INT
) COMMENT 'hello2'
WITH (
  'connector' = 'print'
)

```

`DESCRIBE` statement shows column level props, such as column's comment.
