If you don't know how to access your database on your server, it may be simpler to use manual SQL queries to drop the unneeded table(s).

For each table you want to remove, run the following manual SQL query:

DROP TABLE 'table_name'

where table_name is the name of the table you wish to remove.

Note: Of course, make a backup of your database first before performing these queries in case something goes wrong.

What I meant by my second comment was directed towards the authors of the products themselves (not you)...there should be uninstall code that removes created tables and added columns, etc. when a product is uninstalled. This way when a user uninstalls a product there are no database changes left behind that are no longer needed.
