You can't view mysql tables with a word processor, they're in a proprietary binary format. DON'T go deleting any tables until you're 100% sure they're corrupted to hell and back (which is probably unlikely)... and even then I'd rename them and keep them anyway.
Do you have SSH access? Or is Phat a fully managed host? If you have SSH, try this...
mysql -u <username> -p
... enter your password ...
use <database_name>
check table <table_name> <-- repeat as many times as necessary
If any tables show up errors,
repair table <table_name>
