Hi
If you click on the table you want to export, there is the option view a dump / schema of that table at the bottom of the page (I am not exactly sure what they call it: I have a dutch version). You can then choose to see only the structure of the table. This will create a series of Mysql commands which you can copy. Run these commands in the command box in PhPMyAdmin, for the database you want to create the table in, and the table will be created in that database.
Of course you can choose to export the content of the table as well, which wil then give you alle the commands to insert the data into the new table.
Hope this helps?
Jelle.
