User blog:TheRexVoxian/I need some help with stuff

I've been trying to perk up my wiki main page and I see another wiki making things like this: And I don't know how they make it. I'm kinda new to wikis and I'm not familiar with source code, but how do you make something like the heading given as an example? It's been driving me nuts and the editor identifies it as a table but I seriously don't know how to get it. Is there like a hidden button somewhere or something? What is it even called?
