Larger table built on top of existing table. Extending the sides makes it easier to pull a chair up to the table as well. A router and wood are far cheaper than a new dining table if you have the skills and tools.
My husband made my 10 foot 8 inch farmhouse table. Top made with shiplap. I painted and distressed it. Legs and apron ordered from Osborne Wood Products. But you have to do cross pieces underneath for stability.
