Where can I find this table?
It looks to be home made. If you know someone handy, they could probably make one for you. It is beautiful! Hope you can find it. Here is a tutorial on one that is similar: https://www.hometalk.com/3613641/diy-farmhouse-table-bench
This table does look to be a DIY project though you may have to do some research to see if it is available to be purchased. If you can find where this picture came from -perhaps a magazine--you may be able to trace the source for the table and benches. I could see finding old treadle sewing machine bases and reconfiguring them for a table. You would have to find more than one to make a large dinging room table.
Here's some inspiration to look through!
Oh, boy! Do I have a LOT of options for you!
Well, hammer or available $$ to spend - either one works for me lol!
It is most likely a custom made table. I've seen ads for them on marketplace in the past, made to the size you want.

The bases look like they could also be supports from vintage school desks.
