We installed one of these:

in our dinette area.
Now we have a desk and dinning table that can be used together or separately. My wife is into scrapbooking and card making she likes a big work surface area. So we use a 5ft white plastic folding table with adjustable height and butt it up to the right side of the desk This creates an L shaped work area for her at the desk. We move the dining table into the floor area like shown in the first photo.
This setup makes for a flexible work space we can rearrange to fit our needs.
