A view needs at least one column whereas a table doesn't...

The first SQL command throws an error whereas the second one runs fine:

edb=# create schema s1 authorization u1
edb-# create table t1() create view v1 as select * from t1;
ERROR: view must have at least one column
edb=#
edb=# create schema s1 authorization u1
edb-# create table t1( c1 int ) create view v1 as select * from t1;
CREATE SCHEMA
edb=#

I know the ERROR seems obvious, but then if we allow zero-column tables,
then why not zero-column views?

Or should the question be, why do we allow zero-column tables? (is
inheritance the only reason?)

Can someone provide some explanation for this behaviour?

Best regards,
