I had a custom order (from my wife) for an outdoor table.
I made the legs and frame from steel and these were painted a charcoal black. The top was inlaid so that it sits flush.
The top was tiled. It was designed with black square features, surrounded by a white mosaic. Took a bit of time to fit the mosaic together, just like a tricky jigsaw puzzle! But my daughter likes puzzles and she helped a lot.
The table matched the chairs bought for it just perfectly.
