Hi,
thanks for your post, and sorry for the trouble.
Now, to be honest, I don't even see a table there (on the "About" page). All there is is a one-pixel image by PayPal.
You'll simply have to paste the full HTML code from PayPal into the page, that's how I do it.
(As a side note: As these are support forums of the TablePress plugin (to which your question seems unrelated), you might have more luck asking at http://wordpress.org/support/ if the problem persists.)
Regards,
Tobias
