My daughter had about an eight inch table behind the entire length of her couch. It was, indeed wedged against the wall. It would never have survived free standing. These tables are kind of a rage in the decorating books for whatever reason. It's too hard to turn and set your drink on and, other than knick knacks, it's not much use for anything else. But they are in vogue. That said...
I would not cut a beautiful slab of walnut like that until I was dang sure I knew why. If mamma wants a table, so be it. 14" is plenty wide for what she wants. So, you can make her table AND several cutting boards out of fourteen feet! However...
I would suggest you not attempt to crosscut that giant slab with the table saw. Yes it can be done. But instead I would opt to use a circular saw to get the slabs down to a manageable size before using the TS for maybe a final dimension. And whatever saw I used would have a good, sharp blade.
