This table is a puzzler. It is unique!

I'm guessing that it was a work table. Maybe those back "U" pieces held a bolt of cloth or leather. The merchant would pull a length of material from the bolt and cut off on the table top. The rack could hold extra long pieces. I'm giving this guess a low probability because I do not see any expected scratches and wear marks on the table top for this kind of service.

That rack reminds me of a magazine rack.

The "U" pieces remind me that they might have held a heavy roll of paper on a wooden rod or something similar.

I am imagining a roll of "something"...on a wooden rod or dowl, on the back...pulled out over the table top, something done to it...measured, printed, examined, de linted ..or...who knows....then stacked in the spot with the slats....
Or maybe the other way around....freshly dyed fabric. laid in the slatted area, and pulled up and rolled on rollers...?

Interesting that the top cross piece on the slatted portion is bevelled as if something were pulled up (or down) across it.

Why is there a gap between the top of the crossed legs and the table top supports on either side underneath, as seen in photo #3? Does the table fold up or disassemble somehow?

Perhaps it would be useful to know the dimensions of the 'working' table top. From the last pic and 29" height, I suppose it can't be wider than 30". That would seem to be too small for any fabric bolt and leave printing on some paper or other material.

Wow. You all have great ideas! I will take measurements of the tabletop length and depth this afternoon when I get back home. Other clues... There is extra wear on the tabletop immediately on the inside of the U pieces, you can kind of see it in pic #2 to the right of the U piece on the tabletop. The other side has the same wear. Also, on pic #4, you see the extra wear where someone's leg's may have rubbed against the rack.

@colleen No, the table does not fold or disassemble in any way.

To me, the slotted area is almost certainly a place to collect a series of fairly stiff flat product of some kind. If not stiff, then they would curl or flop around and slide off the 'rack'. It is hard for me to imagine something that stiff coming off a roll. I wonder if we have a thin element on a roll that gets laid on top of a stiff rectangular piece such as poster board. The 'poster board' either comes from elsewhere and after manipulation, dropped in the rack; or as per lindac, comes from the rack and after manipulation removed elsewhere for further action.

Am I the only one here with miniature horses? They can be ravenous when you bring them in. Fill the rack up with your best alfalfa. When the hay is all gone the rack can double as a holder for their favorite horsey magazines. :)

I know it's some sort of work surface, with something rolled off a long rod held in the back, into the bin in front. Fabric? Paper?

What a neat table! Can you possibly take some more photos showing the joinery and the underside?

@Sammy I sure can. task pending!

It is not good for puzzles, unless you do all puzzles standing up, Looks like there is no place for a chair.
