Hi,

I can't take a picture of it closed. Sorry, the height is 42" square x 29"H.

The height is 29"H.

Does it not close or you just don't have photo capabilities?

There are a lot of things on top of it right now. Somehow it closes underneath itself, I haven't tried to close it completely, if you pick it up it will close inward.

Maybe it had a leaf insert at one time.

No worries. I think I can tell from the photo underneath that it has an accordion action and is missing the leaf(ves) it once had.
Based on the photos and information provided, and subject to examination, this is:

A provincial Regency style turned pine accordian-action extension dining table
Possibly English, 20th Century
Appears to be lacking leaf insert(s)
29 inches high, 42 inches wide by 42 inches deep (closed)
$400-600*
