This image shows some kind of simple table that could be converted to a wikitable. Storing tables as images makes it harder to change (update, translate, …) them. Wikitables also help making sure to be consistent in font and size.

This SVG image was uploaded in a graphics format such as GIF, PNG, JPEG, or SVG. However, it consists purely or largely of information which is better suited to representation in wikitext (possibly using MediaWiki's special syntax for tables, math, or music). This will make the information easier to edit, as well as make it accessible to users of screen readers and text-based browsers.
