This is a very simple one. https://www.hometalk.com/37768774/bbq-table
it all depends what you have but I will just use wood ... Criss cross 2x4 as a legs and then build top by simply fastening 2x4 together on the bottom.
Make sure you use Fireproof surface - Concrete Slabs on top of timber should be okay!

This is on my to-do list too. Do an internet search for DIY grill table, you'll find lots of fabulous ideas as I did.
