You can directly take small tables with similar heights and put them together. You can also go to the building materials market to buy back the wooden boards made of the same material as the original table, cut them into two pieces as required, then connect them on both sides of the table, install hinges, and add movable small brackets to make a new table that can be lengthened in time. The specific transformation process can refer to the samples of furniture stores. If you find a carpenter, give him the plan.
