Using SQLPlusPlus (freeware) you could generate a script to alter a table to
your heart's content.

For example to alter DEPT table, we could generate the following script.

SQL> EXEC S2.BLDALT('DEPT','SCOTT')
| ----------------------------------------------------------------------

---

-
| ALTER TABLE scott.dept DROP CONSTRAINT sys_c0014552;
|
| DROP INDEX scott.sys_c0014552;
|
| RENAME dept TO dept_old1234;
| CREATE TABLE scott.dept(
| deptno NUMBER(2,0) NOT NULL
| ,dname VARCHAR2(14) NULL
| ,loc VARCHAR2(13) NULL
| )
| PCTFREE 10
| PCTUSED 40
| INITRANS 1
| MAXTRANS 255
| TABLESPACE system
| STORAGE(INITIAL 102400
| NEXT 102400
| PCTINCREASE 1
| MINEXTENTS 1
| MAXEXTENTS 300);
|
| INSERT INTO scott.dept(
| deptno,
| dname,
| loc)
| SELECT
| deptno,
| dname,
| loc FROM scott.dept_old1234;
|
| ALTER TABLE scott.dept ADD CONSTRAINT
| sys_c0014552 PRIMARY KEY (
| deptno
| );
|
| CREATE INDEX scott.sys_c0014552 ON SCOTT.DEPT(
| deptno
| )
| PCTFREE 10
| INITRANS 2
| MAXTRANS 255
| TABLESPACE system
| STORAGE(INITIAL 102400
| NEXT 102400
| PCTINCREASE 1
| MINEXTENTS 1
| MAXEXTENTS 300);
|
| GRANT DELETE ON scott.dept TO public;
| GRANT INSERT ON scott.dept TO public;
| GRANT SELECT ON scott.dept TO public;
| GRANT UPDATE ON scott.dept TO public;
