Parser functions will mangle wikitable syntax and pipe characters ($pipe), treating all the raw pipe characters as parameter dividers. To avoid this, most wikis create the template    :! with its contents only a raw pipe character ($pipe). This 'hides' the pipe from the MediaWiki parser, ensuring that it is not considered until after all the templates and variables on a page have been expanded. It will then be interpreted as a table row or column separator. Alternatively, raw HTML table syntax can be used, although this is less intuitive and more error-prone.
