Forum:Table as a template parameter

I made a simple template that creates a div box around a given parameter. Basically this:

Now I'm trying to put a table as the parameter, and it doesn't let me. I assumed that using the ! template in the table would have solved it, but it doesn't.

The table works if I don't add any styling to it, but as soon as I start messing with borders or anything it breaks.
