CREATE TABLE new_table ( field definitions);

INSERT INTOP table_name

   SELECT *
   FROM old_table;

DROP old_table;

Actually you can do this by making changes in the data dictionary tables but I don't put that type of advice into a newsgroup where someone might accidentally destroy a system. The main advantage of the above is that it allows you to resize the initial extent size to more accurately reflect the data in the table.
