> In FLINK-14665, we supported computed column in planner. However, the implementation of {{TableSourceTable#getRowType}} will include computed columns which is possibly not right, because computed column is generated in the downstream Project, not in the source scan. 
> This is possibly lead to errors when push project into source scan which will call {{TableSourceTable#getRowType}} in the rule. Currently, all the tests are passed because we don't have a test to cover this, i.e. computed column on a projectable TableSource. We should at least add a test to cover this.
