Small Spoilers?

[MadisonCrossing]

Every now and then, I'll see what looks like a small spoiler in someone's signature. It looks like the normal spoiler, just a bit smaller. Could anyone tell me how to use them?​

Tables.
[table="width: 500, class: grid"]
[tr]
[td][spoiler]What's up?[/spoiler][/td]
[td]Hi hi hi![/td]
[/tr]
[/table]

What it will show up as:

[table="width: 500, class: grid"]
[tr]
[td]

Spoiler

What's up?

[/td]
[td]Hi hi hi![/td]
[/tr]
[/table]
