Funnily enough I have been looking at tables too - the Coleman ones seem as good as any. I agree with Steve that the stools that come with that set are rather fiddly. You're better off with proper chairs IMHO.
Depending on what your requirements are (will it be used on expedition where you're moving everyday and space is at a premium and ease of packing away is important vs going camping and wanting space to set everything up) I came up with the following options.
For minimal space requirement in the truck and convenience, the Coleman
Mini Camping Table looks good. A similar alternative is this one from
Quest. The Quest one is similar money, so I'd go for the Coleman but that's down to individual preference.
Folded up, these tables are around 40cm x 40cm x 5cm so very small and convenient when folded up - easy to pack! But they're not going to do much other than hold a cooker or allow 2 people to eat in comfort. This one gets my vote for the "lightly-loaded" boys weekend away or for basic table functionality on an expedition.
When setting up in the same place for a period of time, I reckon the
Coleman "Table for 8" hits the mark. It has a relatively large "footprint" at 76cm x 76cm x 8cm but it'll fit under/on a roof-rack or can go at the bottom of the boot, so doesn't take up too much packing volume. It provides a lot of space for cooking, setting up cookers, stacking kitchen stuff etc. while camping - quite important when you have a family of small children
It's nice and sturdy and is simple to assemble/dismantle. But having to pack it in the truck every day if on an expedition would be tedious (unless you had a convenient slot under the RR or similar) so I wouldn't advise it unless you really want/need the table space.
Hope that helps
really don't know why I bought the other flimsy thing should have just stuck with this 
I've seen and handled the Quest mini table and it's a reasonable piece of kit, stable and well put-together -I would think the Coleman is better though, hence I will go that route.
