14757	Add An Example For .extra(tables=[])	Mike Shultz	nobody	"When fiddling around trying to find a solution to one of my problems, it seems to be that .extra(tables=[]) was what I needed.  I took a trip through the django documentation just to find that there were no examples, or even a description into what kind of 'string' it takes.  Is it JOIN statements?  Just a name of a table and/or matching columns?  

Please add an example to the documentation and/or a better explanation of the string it accepts.
