Just put a label include it as a binary file at the end like this:
mytable: .incbin "newtable.nam"
Then you can use the label mytable in your main code to refer to the start of your nametable data whenever you need to. For a complete tutorial, go to the main page, and there is an offsite tutorial link done by Michael Martin. I found his "loading large nametables" section most helpful (I think its day 23 or something).
