The legs look similar to Piet Hein designs, but I think he usually used four rods per leg. The Hein table tops are also usually elliptical. 

sorry, didn't mean to exclude Arne and Bruno from their design credit. https://fritzhansen.com/en/designers/Piet%20Hein

I found another one but also unidentified:  https://www.vntg.com/136014/danish-design-table-1970s/

The board looks very similar to ones produced by Lau Lauritsen.

Maybe it's Gangsö, made in Danmark.

Yes, the legs are similar. I am sure I did not find all the tables from Gangsö but the ones I saw have elliptical tabletops and not boat shaped ones.

Its interesting how the parts used for the extension mechanism or the legs seem or are partly the same across manufacturers.

The legs look to be fairly recent.  The three-rod design ending in the rounded foot with rubber base looks like legs found on some recent tables, like this "House" model sold by British retailer John Lewis.  Maybe a Danish top fitted with new legs?

@mark737 yes, it looks like the same legs, even the extension mechanism is very similar to the Lia table. But the legs are screwed into metal sockets, that would be a very lucky fit for new ones.

Is it possible that John Lewis had a Danish manufacturer at some point?

Or of course someone just put the DFC tag on the table.

@robert  Yes, the "Lia" table from their "House" collection, and I guess the foot levelers are plastic not rubber.  What do you mean by "the legs are screwed into metal sockets"?  On your table the three rods look to be welded to the flat plate which is attached with four screws to the table underside.  I did not see a picture of how the Lia table attaches, but I'd assume it's the same.    

Edit: And a furniture store in Singapore called Hipvan is selling a table with what appears to be the same legs.  They call it the Rikku.  Whatever company makes these legs probably sells them to various manufacturers around the world.
