corsarick, most pine with a natuaral finish (like that table) warms up to those nice uneven amber tones over the years. Why you want to camoflage that gorgeous chest to blend with your floors is beyond me...but! Since you asked.
Try buying a few of the small pint cans of available stains. Whenever I'm matching tones I usually end up combing two or sometimes three different colors. A can of walnut stain is not going to instantly make that pine look like your walnut flooring, so you may need to experiment if you want a match as close as possible.
Take your time, buy some pine board shorts from any of the homecenters for testing your colors. When layering stains, I rarely wait for one color to dry before applying the next so that they blend nicely. Of course you'll have to knock the sheen off the chest first before applying anything directly to the wood to achieve some sort of penetration.
If you buy Minwax stains I'd start with a can of walnut, jacobean and provincal.
Good luck.
