How to create a view or maybe report combine the items from 2 tables?

Those SO answers are not that great in the sense it is encouraging you to use low level DOM manipulation to create a simple table. I think it is important to know JavaScript at that level but I would never do so unless I was creating a library. Libraries like jQuery, Mustache and Underscore allow you to work at a much higher level and all of these libraries are used by QuickBase. I don't understand firewall issue as you can run your code from user defined pages hosted within the QuickBase domain.
