=== Tables in parameters === <!--T:227-->

<!--T:240-->
Since the pipe character (<tvar name=1><code>|</code></tvar>) and equality sign (<tvar name=2><code>=</code></tvar>) have different meanings in template calls and wikitables, in order to use table markup in the value of a template parameter one generally needs to "escape" those characters (i.e., protect them from interpretation as template markup) using special sequences:

* <translate><!--T:255--> the built-in  <tvar name="2"><code><nowiki></nowiki></code></tvar> provides an "escaped" version of <tvar name="3"><code>|</code></tvar> since MediaWiki 1.24</translate>
* <translate><!--T:242--> the built-in magic word <tvar name="1"><code><nowiki></nowiki></code></tvar> provides an "escaped" version of <tvar name="2"><code>=</code></tvar> since MediaWiki 1.39</translate>

<translate><!--T:251--> Before the introduction of these magic words, many wikis used templates to accomplish the same things.</translate>
<translate><!--T:252--> On such a wiki, the magic words take precendence over the same-named templates.</translate>

====Example table==== <!--T:243-->
</translate>

{| class=wikitable
!A!!B!!C
|-
|A1||B1||C1
|-
|A2||B2||C1
|}

'''<translate><!--T:244--> Table code:</translate>'''

<syntaxhighlight lang=wikitext>
{| class=wikitable
!A!!B!!C
|-
|A1||B1||C1
|-
|A2||B2||C1
|}
</syntaxhighlight>

'''<translate><!--T:245--> Escaped table code:</translate>'''

<syntaxhighlight lang=wikitext>
 classwikitable
!A!!B!!C
-
A1B1C1
-
A2B2C2
}
</syntaxhighlight>

<translate><!--T:246--> Note that the first left-brace (<tvar name="1"><code>{</code></tvar>) is interpreted as a literal left-brace character because it is immediately followed by the <tvar name="2"><code><nowiki></nowiki></code></tvar> magic word.</translate>
<translate><!--T:247--> Similarly, the last right-brace (<tvar name="1"><code>}</code></tvar>) is interpreted as a literal right-brace character because it is immediately preceeded by the same magic word.</translate>
<translate><!--T:248--> However, in some cases these brace characters do cause problems, so some wikis provide templates for escaping these characters, as well:</translate>

* <translate><!--T:249--> the template call <tvar name="1"><code><nowiki></nowiki></code></tvar> might provide an "escaped" version of <tvar name="2"><code>{</code></tvar></translate>
* <translate><!--T:250--> the template call <tvar name="1"><code><nowiki></nowiki></code></tvar> might provide an "escaped" version of <tvar name="2"><code>}</code></tvar></translate>

<translate><!--T:253--> Some wikis go even further and provide other convenience templates like <tvar name="1"> (<code><nowiki>{|</nowiki></code>),  (<code>|}</code>),  (<code>||</code>)</tvar>.</translate>
<translate><!--T:254--> On such a wiki, the code can be simplified a bit to this form:</translate>

<syntaxhighlight lang=wikitext>
 classwikitable
!A!!B!!C
-
A1B1C1
-
A2B2C2
