Wikipedia type table

I am working on a webpage that I might extend into a full blown private website(in other words a website that works but I don't publish online). I am using notepad++ for this. But I don't know how I should get a table to look like a table on wikipedia that is at the top of certain pages. Obviously, I will probably have different types of things in the table than Wikipedia does but I don't know how to do that table at the top of the page.

Here is an example of what I am talking about:

How do I make a table in that format using just HTML and CSS? I was able to do it once but I lost the code and don't remember how I did it.
