Much easier to do if your table was available in drop pocket and ball return configuration originally. If you have a furniture style table, it's most likely not doable due in part to how thin the rails are. When there's a will, there's a way but what are you chasing?
I did it for $12 back in the early 1990s to a different mfg table, American Heritage, with a short skirt.
Took about an hour for the returns, 1 hr for the tray.
The returns were dark brown and blended well with the dark wood.
