Template:(!

{|

Template documentation follows
Note: the template above may sometimes be partially or fully invisible.
Visit "Template:(!/doc" to edit its documentation if it is available. (How does this work?)

Template:Documentation subpage Template:High-use This templates produces the {| sequence (i.e., start of wikitable), so that wikitables can be built inside templates.

Explanation

The problem is that if a pipe character "|" appears in a template, the template parser assumes that the pipe is part of the template; and so if there is a table within a template the pipe symbols that are usually interpreted as part of the table syntax will be interpreted first as part template.

To prevent this happening it is possible to "hide" the pipe character of the table from the template parser by substituting {{!}} for a pipe character.

To aid with building a table there are some additional template which can be used to help

• {{(!}} for {|
• {{!+}} for |+
• {{!-}} for |-
• {{!!}} for ||
• {{!)}} for |}

See mw:Help:Magic words § Escaped characters and mw:Help:Templates § Using pipes in parameter values
