Template:!!/doc
 | This is a documentation subpage for Template:!! It may contain usage information, categories and other content that is not part of the original template page. |
 | This template is used on approximately 248,000 pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This template should not be substituted – use {{!!}}. |
This is an auxiliary template that allows one to encode "||" (two pipes or vertical bars) within template parameters. If this does not need to be interpreted as wikitext (i.e. table cell separators), it is better to use "||". However the "||" delimiter for a wikitable has to be escaped by a template if it is used within a template.
This template extends the magic word {{!}}, which is used to escape a single vertical bar character.
Notes
[edit]There is usually no such problem with "!!" (exclamation marks). This problem only affects "||" (vertical bars) in conjunction with the Help:Parameter default mechanism within tables. However, in table rows starting with "!" there can be problems with "!!" being interpreted as a cell separator. Try replacing it with "!!".
