Is it possible to find and get rid of duplicate rows easily?

Olivia Lippincott shares a tip from Byron Wingerd for an easy way to find and get rid of duplicate rows. Join the table to itself (Tables>Join), match all columns, drop multiples for the Main and With Tables, and then save the joined table with a new name.  (Saving with a new name is most always better than renaming or changing in place because it allows you to examine the changes and assure they reflect what you really wanted to do.)
