Regular dining tables are fixed size or extendable but normally only on one or two sides. The idea behind this table is that it’s extendable per seat, so with individual drawers.
In non-extended position it can be quite a small table, measuring for example 60cm. With all drawers extended, it can be as much as 120cm with enough room for pots and pans in the center. If the drawers will be flush or have space in between, what the dimensions of the table are, etc, etc, etc, that’s really for a later more detailed design.
