Those ends are appropriately called "breadboard ends." Here's a video showing one approach to making breadboard ends -- http://www.popularwoodworking.com/video ... board_ends --
When you look at the video, what it doesn't say (but is probably in the magazine article he refers to) is that the holes in the panel are elongated (more like slots) to allow for expansion and contraction of the panel with moisture swings.
If you do a google search on "breadboard ends" I'm sure you finds lots more on the subject.
