Cannot add a new column without a default value in a table, even the column is not set "Not Null" constraint enabled.

1.create new table or edit an existing table.
2.add a new column, input cloumn name and data type. then you will get an error prompt like that
" The value ("") cannot be parsed. Please check if the value you input matched the "INTEGER" data type, or its length does not exceed the limit."
3. the "Not Null" constraint chekbox seem no help for the error. The bug cause that column can be added only when it has a default value.
