Does adding a new column in the table affect the data source?
and to add to Phil's post; you don't have to have a new table. The new calculated column can be ignored in terms of visuals you might build
however if the calculation involves a distinct value where the result is less records than the original table, such as a single sum for an overall category - it might be more useful to have a new stand alone table (you can join them)
and in either case you can undo these steps in your Query Editor should you need to experiment without affecting your core table
