It can be constructed within an expression using the [[~[~] syntax>>MediaWiki.NULL]]. It may also be generated by special actions and conditions, and there are actions that can [[insert or remove values>>MediaWiki.NULL]].

690 690  Tables are associative arrays - they are like lists, but you can assign values to (almost) arbitrary keys, not just to index numbers. A table is constructed within an expression using the [[table~[~] syntax>>MediaWiki.NULL]]. See the section about [[value properties>>MediaWiki.NULL]] for how to access the contents of a table. [[Creating and removing entries>>MediaWiki.NULL]] works similarly to lists, but instead of inserting, you simply assign a value to a table key. If the key does not exist yet, it will be created.\\
