今天的一道题：https://www.modb.pro/test/20220907

但我查了http://dba-oracle.com/t_tablespace_extent_management_local_uniform_autoallocate.htm，上面说extent_management和segment_space_management待表创建后一律都无法修改啊。

从语法里也没有看到可以修改的语法：

https://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_3002.htm#:~:text=1%20Take%20the%20tablespace%20offline%20using%20an%20ALTER,with%20the%20ONLINE%20clause%3AALTER%20TABLESPACE%20tbs_02...%20See%20More.

求解答。
