Okay what is the size of the space .You need drapes that fit to the floor BTW and lighting that does not make everything yellow and no fan in a DR.just a nice chandeleir.

Table does not look big for me. What is odd in this room is bench under the window next to chairs.You might want to move chairs this way

The size looks correct. Put a bench on each side and the chairs at the ends.

You didn't ask, but your curtains could use some length.
