Well that is really annoying. Isn't it? This often happens when you want to alter a table: change data type on existing columns or change allow null on existing columns.
Good, so how do you get rid of this warning: Saving changes is not permitted ?

3.Click Designers
4. and Uncheck 'Prevent saving changes that require table re-creation' option
5.Go OK and retry alter your table.
