I love the shape of the RH table in the first post, but not the finish.
I think, based on the examples posted, this room actually has a somewhat formal and classic feel (blue walls w/ white trim, classic chandelier, etc).
I'd stick with the simple pedestal style, but in a darker finish. Something like this:
"Alexandra" Dining Table & "Carolina" Seating - Horchow
But with your lovely chairs.
Unfortunately this table is currently unavailable.
The other table I like for this room would be this:
"Bento" Dining Table & "Peacock" Chairs - Horchow
But it's 72".
