[Mediawiki-l] Using Winter to hide text

[Juan Jesús Cremades Monserrat]

Hi!

I've created the next code into a Template.

{{#if | {{{tablas|}}} ||
== Tablas ==
}}

"tabla" is invoqued in a page like this:

{{Template_Name
...
tabla =
}}

Without text. The objective is that the "Tablas" title will not apeear in
the page, although it works, the problem comes in the Table of contents,
where I see the next:

1. Section A
2. Section B
...
6. Tablas
...

How can I delete this link when 'tablas' is void? Thanks!
