Planning on doing 2 rows with each having a 4x8 table. The question is can I use just 1 pump and 1 res to do this or will each table need its own?

Can you use 1 resevoir for Multiple Flood tables?

Yes you can share tanks with Hydro systems, just make sure you have eniough capacity to feed the plants you have without getting big changes in pH or CF.... The smaller the reservoir, the larger the swings... You also loose the ability to put the table over the res, reducing the chances of Flooding and you will also have tubes around that are also a possible source of leaks. In some setups, climates, the warmth from the res beneath can be a help or a hindrance too, so take care..

Yes you can !
as long as your pump is strong enough and your res big enough don't see why it couldn't be done
happy growing and im sure pics of that type of setup would be beneficial to the site/thread

You can use a single reservoir for multiple flood tables provided all plants are in the same stage of development. Obviously with different stage (clones vs. veg vs. flowering) and size plants, they would all have different nutrient requirements. If you are planning on having one reservoir running multiple flood tables, make sure your plant stock is approximately the same age.
If you're using a single reservoir for multiple flood tables with plants all in the same age of development, as ChaosCatalunya pointed out, you'll see a smaller range of PH and EC swings as you fine tune your plants consumption and feeding.
An excellent way to figure this out is to provide a fixed amount of nutrient and monitor the EC and PH swings. If the EC rating has gone up at the end of a 24 hour period, it means the plants are consuming more water than nutrient. If the EC rating has gone down at the end of a 24 hour period, it means the plants are consuming more nutrient than water. An ideally adjusted ratio of water to nutrient would see smaller EC swings (1200ppm might see 10% loss to 1080ppm over 12 hours, however a 1% adjustment would see 1200ppm at 1188ppm). The perfect ratio is when your EC rating stays steady, example at 1200ppm but your reservoir is being emptied. This means the water/nutrient solution is balanced close enough that all you can see is the reservoir being emptied
