Anna, it looks fine on your site.
You'll probably have to make the Placeholder height fit your page.
The site has lots of settings for switching on and off aspects of the table so refer to their examples.

Obviously you'll have a manual overhead if you keep the data within the application placeholder but if you are updating weekly,say, that might not be too troublesome.
I am sure your PHP developer will be able to provide a suitable connection to your server data.
