Table with variable columns

[eluser]Jacob Graf[/eluser]
That's what I have now. I have a table called devices and a column for each feature. The problem is not in querying the database for phones that match that criteria, the problem is in the checkboxes that determine if the columns show up on the report.

So consider this, with the way I'd like it to work, you could query the database for phones with a qwerty keyboard, but you may not necessarily want that to show up on the report (for printing/clutter purposes)

So now that I have all my data, how do I build a table based on which columns the user wants to see on the report?

Thanks for your help. I look forward to your response!
