I seem to remember another "finishing" thread where every respondent had their own favourite finish. Mine is Danish Oil by Rustins. Easy to apply easy to repair or refinish. It also enhances the figure or grain of the wood. If the table is for outside there's nothing that will survive the ravages of sun, wind and rain for very long; so I would go with something that can be refinished with the minimum of effort - like Danish Oil.
You can thin the first coat if you wish - it aids penetration, supposedly, and saves using too much of the oil on that initial coat.
A very light sanding between coats and dusting it off will remove the "nibs" and then apply the final coat with something like an ultra-fine Scotchbrite pad.
