Strip table tags from WordPress

Not sure where to start looking for this and I’ve done some preliminary searches on the subject but nothing concrete.

I am currently working with a client who’s initial designer setup their content for WordPress with TABLES (boo!!) inside of the Pages section of the WP Admin area. Is there any way to strip those tags out? Perhaps with PHPMyAdmin or another way? I want to take out all “<table><td><tr>” etc… but leave the “<img>” tags in place.

I thought I’d ask to see if there is anything out there that could do this or perhaps a way to do it with MySQL 🙂

Thanks in advance for your help!
