Template:Ref/doc

Originally from Hello Project Wiki There are many ways to use Ref and Note. Among the simplest is: {| border="1" style="border:1px solid #AAA; border-collapse:collapse; width:80%;" ! style="background:#F2F2F2;" |Article ! style="background:#F2F2F2;" |Wikitext Text that requires a footnote.
 * style="background:#F9F9F9;" |
 * style="background:#F9F9F9;" |

Alternatives
You can also consider using the  and   tags instead like this: {| border="1" style="border:1px solid #AAA; border-collapse:collapse; width:80%;" ! style="background:#F2F2F2;" |Article ! style="background:#F2F2F2;" |Wikitext Text that requires a footnote.
