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 |- but in this case it is probably easier to use {{!}}-
{{!!}} for ||
{{!)}} for |}
