The "body" item of the dictionary must be a callable that takes the row
object and outputs a web2py string or web2py HTML DOM element. It cannot be
a list of functions. If you want to generate a set of links, generate them
all in a single function and wrap them in CAT() or DIV() (or whatever works
for the desired layout within the table cell).
