If those are SQL tables you want to delete, you can do it through Management Studio.
Open your database, expand tables, and you might find it useful to go to "View" -> "Object Explorer Details" to see all the tables in a different pane. You can then sort by date, if that's helpful, and see everything created recently.
Then use CTL-Click to select the specific tables to delete.
Be VERY CAREFUL if this is production.
