Sure. Framing is a technique in composition where objects in the photo direct the viewers attention by covering (usually) one or more edges, creating a sort of frame-within-the-frame. In landscape photography, this is usually foreground trees or rocks — but it doesn't have to be. It could be a building, or even people. In Raphael's Sistine Madonna, the figures to the left and right and the cherubs below (more famous than the whole!) frame the subject — mother and child

This, of course, is no still life, but it illustrates the principle: framing isn't restricted to landscapes.

In a still life, framing might include cloth drapery, the edge of a table, a doorway... any element that isn't part of the main subject but serves as, well, a framing device for it.

This example (The Juice of Life, CC-BY-SA Esther Spektor) demonstrates this — here, the curtain and the edge of the window provide framing for the arrangement on the table.

Of course, here it's somewhat subtle and the framing objects are not in the foreground; a more overt use of framing might be looking through an open window, where the window's literal frame would serve as framing in this sense, too.

("Framing" also has a different sense, the relationship of the entire photograph's rectangular frame to all visible elements — in that sense, of course, all photographs exhibit framing.)
