You can flip over a wire frame trash can and attach it to what ever surface you're keeping your plant on. It might look TRASHY lol though. Because it's a table, I'd use the adhesives that they make for temporary wall hooks. Easy to install, easy to remove. There's tons of other wire sheets/ frames you can look into, too.
Super cheap method: buy some chicken wire and make a dome.

My Yorkie really likes "krusty kraaaaaab, pizza, is the pizza for you and meeeee."
