I agree with everyone here that the original pics you had are a bad choice. Light output, lumens, wattage, whatever, from a small point source would be a poor choice, due to the shaded spots that would be cast by every ball that isn't directly below the fixture. Brighter light output would worsen this situation, due to the bigger difference between the lighted areas and those that are shadowed; and I'm figuring this would also be the issue with darker shades of cloth.
Here are my suggestions:
Go for the biggest (lamp count and length) surface mount flourecent fixture that the room/area (not the table) will allow for, aesthetically. The decorativeness

s) of the fixture is open to your tastes, and there are enough being manufactured that something will look good; as long as you are willing to to shop around and do some research.
That's my permanent light suggestion. I'm assuming that the light will be centered over the table, which would put the light out in the middle of a rather large living area. Unless this area could be used by someone else in the future as a dinning area, those fixtures you chose wouldn't look right come time you do rent it out. Those lights are typically used as a decorative task light, specificaly for a dinning table or foyer area; but of course this my opinion, albeit a professional one.
Now, if you are willing to change fixtures latter on, but aren't liking the idea of having to do some drywall patching covering up the hooks that would be needed swagging alot the of traditional pool lights out there, there are a couple of options.
One, you can find larger lighting bases that will allow you to swag the ends of the fixture from the base itself. This way, the entire fixure would be supported by the same two screws that would hold up any fixture you use (weight might be an issue here, and might necessitate the need for a fan-approved light box with 10/32 screws.) These bases will be a longer oval shape, and will have the hooks on the ends for the chain. The dissadvantege here would be that you might not find this base in a pool fixture you would like to use, but a lighting supply house might be able to supply one without having to purchase an entire fixture.
Two, and this would be an easier and cheaper option, would be to go ahead and mount up some swag hooks in the ceiling, making sure that the hooks are close enough to the light box/junction box that you could cover up the holes in the future with a
ceiling madallion. This option will limit you in the future as to the type of fixture you can use. It will have to have a 4" (give or take) canopy/base and allows the fixture itself to stand off the ceiling, like a chain type fixture. If you can see how the medallion works, you can understand what I am saying with the fixture you will be able to use. Of course if you plan on replacing the "pool" light with a fixture with a large enough base that it would interfere with a medallion, it could possibly be big enough to cover the holes in the ceiling by itself if you mount the swag hooks close enough together.
I apologize if this sounds like rambling, I should have went to bed a good whila ago.

Whatever you choose to do, I hope it works out for you.
