bombas79,
The easiest way would be to write a form for someone to submit, instead of editing the table itself.
The user would submit the form, and it would save to the database, then instead of having static values on the table, it should pull from the knowledge base.
You can see a tutorial at w3schools that will get you started.
I would recommend reading up on SQL Injection.
