One of the key policies of Wikipedia is that all article content has to be '''verifiable''' i.e. supported by a '''reliable source'''. All quotations and any material whose verifiability has been challenged or is likely to be challenged must include an ''inline citation'' of a source that directly supports the material.
Tables are a commonly-used way of displaying information, particularly in articles that consist of lists. As with all things on Wikipedia, however, they require some explanation. This tutorial aims at providing a guide on how to make tables: if you are looking for the policy on when to use them, the [[Wikipedia:Manual of Style/Tables|Manual of Style]] may provide what you're looking for :).
If you are adding such new content, it is your responsibility to add source information along with it. Material provided without a source may be removed from an article. Sometimes such material will be tagged first with a {{tl|citation needed}} template to give editors time to find and add sources.
If you have the enhanced editing toolbar
This tutorial will show you how to add inline citations to your articles, and also briefly explain what counts as a reliable source.
