Hint and Tips

Use `<div style="padding-left:...;">` to indend easily a pre, source or blockquote block: * Look at my indented block: <div style="padding-left:2em;"><pre> Some PRE text ... some more ... Let's finish here </pre></div>	Look at my indented block: Some PRE text ... some more ... Let's finish here
Use `__TOC__` to control the location of the Table Of Content. This is particularly handy when there are some texts before the first heading in a page, and you want the TOC to appear first.
Use `#REDIRECT [[Some Page]]` to automatically redirect a page to another page

Tables

Basic syntax for table is

{| [opt-table-attr] 
|- [opt-line-attr]
|[opt-cell-attr |]Orange
|[opt-cell-attr |]Apple
|- [opt-line-attr
|[opt-cell-attr |]
|[opt-cell-attr |]Pie
|- [opt-line-attr
|[opt-cell-attr |]Butter |[opt-cell-attr]| Ice cream 
|}

Table can be easily formatted using templates like:

{| {{Prettytable}}
|-
|{{Hl2}}|First
|Second
|-
|Third
|{{Hl2}}|Fourth
|}

First	Second
Third	Fourth

Or better yet, using CSS (eg. see MediaWiki:Common.css) class wikitable (see Table):

{| class="wikitable"
|-
!First
|Second
|-
|Third
!Fourth
|}

First	Second
Third	Fourth

Cell content can be formatted for each cell individually or for all cells on a same row

{| class="wikitable"
|-
!Very long header
!Very long header
!Very long header
|-
|align="left"|left
|align="center"|center
|align="right"|right
|- align="center"
|center
|center
|center
|}
|}

Very long header	Very long header	Very long header
left	center	right
center	center	center

Using Extensions

Raw File

See reference syntax here

Example without anchor (best choice when block immediately follows the link).

Download [{{#file: HelpRawScript.sh}} this file].
<source lang="bash">
#! /bin/bash

echo 'Hello, World!'
</source>

Download [{{#file: HelpRawScript.sh}} this file].

#! /bin/bash

echo 'Hello, World!'

Example with an anchor (necessary when there is intermediate block - but need keeping name in sync!).

When anchor is on another page, use notation {{#fileLink: myscript.sh|Another Page}}

Download [{{#filelink: HelpAnotherRawScript.sh}} this file].
<pre>
This block is just to confuse RawFile
</pre>
{{#fileanchor: HelpAnotherRawScript.sh}}
<source lang="bash">
#! /bin/bash

echo 'Hello, World!'
</source>

Download [{{#filelink: HelpAnotherRawScript.sh}} this file].

This block is just to confuse RawFile

#! /bin/bash

echo 'I said "Hello, World!"'

For very long text, it is possible to hide the file content using CSS style="display:none"

Download [{{#file: HiddenRawScript.sh}} this file].
<div style="display:none"><source lang="bash">
#! /bin/bash

echo 'Hello, Wonderland!'
</source></div>

Download [{{#file: HiddenRawScript.sh}} this file].
