It would have helped considerably if you had provided the pictures indicating it was a butterfly-leaf table when you first posted.
I would still say this falls within what is variously known as Renaissance revival, Jacobean revival, Flemish revival and various other terms which began appearing in America from around 1870 onwards. Companies such as Berkey & Gay of Grand Rapids, Michigan popularised the style using designs produced by John Keck and progressively adapted them for more practical use in American homes. The butterfy-leaf extension is such an adaptation and I would think puts this table somewhat later.
Most usually, butterfly leaves like that operate to make an already-wide table longer (to accommodate more seated guests at dinner for example); rather than wider such that a narrow console table can also serve as a dining table if needed, but without taking up too much space.
B&G noted in their 1910 advertising pamphlet ‘Character in Furniture’:
In the present revival of the Seventeenth Century styles in furniture, two interesting factors may be noted; the opportunity to study at first hand a neglected period in design and the wider range and variety presented to the prospective buyer. A few years ago it was almost impossible to find furniture of Seventeenth Century pattern. The few pieces were expensive antiques, little suited to an American home. When furniture-makers turned their attention to this interesting period a rich and attractive field was presented for the first time to the general public. "Flanders" is the trade name chosen by the Berkey & Gay Furniture Company to designate a style which they have adapted with marked success, using the strong, sturdy characteristics of the late Sixteenth and early Seventeenth Centuries.
If this table were from B&G or one of several other leading makers it would for sure be marked, so I would assume it’s from a lesser maker jumping on that bandwagon and from around the same era. Say very late 1800s through to about 1930 at the latest.
