The magic word {{!}} is used to escape a vertical bar character "|" in wikitext markup, causing the parser to temporarily not interpret it as a special character.

This used to be a template, but for speed reasons, the MediaWiki parser was changed in July 2014 to instantly interpret {{!}} as "|" and ignore this template, making {{!}} a magic word. You can continue to use the code in exactly the same way as before.

Do not use syntax like {{Template:!}}, and do not supply a parameter, for example {{!|foo}}. In those cases, the template transcludes as an error message: Error: The retired template {{!}} has been transcluded; see mw:Help:Magic words#Other for details. To fix this, use only the code {{!}} to generate the | character.


Usage

The code {{!}} is used to escape the vertical bar character, |, so that it is interpreted later than it would be otherwise. This is mostly useful when trying to include a table in a template. For example,

{{cquote|text=
{| class="wikitable"
|+ Caption text
|-
! Header text !! Header text
|-
| Example1 || Example2
|-
| Example3 || Example4
|}
}}

yields nonsense:

However escaping the bars with this magic word and similar templates gives:

{{cquote|text=
{{(!}}class{{=}}"wikitable"
{{!}}+ Caption text
{{!}}-
! Header text !! Header text
{{!}}-
{{!}} Example1 {{!!}} Example2
{{!}}-
{{!}} Example3 {{!!}} Example4
{{!)}}
}}


For how to include a table in a footnote, do:

Example 1{{refn|group=note|This is a note before}}

Example 2{{refn|group=note|1=<nowiki></nowiki>{{(!}}class{{=}}"wikitable"
{{!}}+Example table with two columns
!A column
!Another column
{{!}}-
{{!}} Some data
{{!}} Some more data
{{!)}}<nowiki></nowiki>}}

Example 3{{refn|group=note|This is a note after}}

==Notes==
{{Reflist|group=note}}

Be careful to follow this formatting, otherwise the table may gobble up the subsequent footnote. This can be unnoticeable if there is only one footnote, only causing an issue if a second footnote is added.

Example 1[note 1]

Example 2[note 2]

Example 3[note 3]

Notes

  1. ^ This is a note before
  2. ^
    Example table with two columns
    A column Another column
    Some data Some more data
  3. ^ This is a note after
