Parser functions will mangle syntax and pipe characters ($pipe), treating all the raw pipe characters as parameter dividers. To avoid this, most wikis used a template $template with its contents only a raw pipe character ($pipe), since MW 1.24 a replaced this kludge. 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.
