Thread:Project:Support desk/Are the information provided on the right side of the page a table?

So for example, look at this page:

https://www.mediawiki.org/wiki/Extension:Cite

On the right there is a table explaining basic facts about the extension. Video game wiki's do the same thing with their video games. How do I do that? Is it just a table? How do I incorporate images into my table? Is there an extension for this?

Thank you for your time and support.
