Thanks for the good comments about the database Oliver, it has been compiled over many years of research, adding information, including other available sources and user contributions as well, making it one of the most complete ports databases online.
There is a table format for some subsets of the ports..
Commonly open ports:

Vulnerable ports:

Is something like that what you had in mind?
We don't want to make the full database available in easily downloadable format, it would just give it away to all kinds of questionable/stale websites around the web that provide no original work, we prefer to keep it in house and updated regularly. It is also huge (nearly 20,000 rows when we include other sources like IANA, Sans, Nmap, etc.), so not suitable for web viewing as a whole.
The current setup is easily searchable by port (lower "jump to" combo box), provides links to related ports where applicable, etc. If you'd like us to improve the UI for ease of use we would definitely consider it, short of making the whole database easily downloadable.
Thanks for understanding.
