DataTables/examples/ajax/defer_render.html
Allan Jardine afdf67075d New: language.decimal option. This option can be used to tell 
DataTables which character is used as a decimal place in the table's
data, so that number which are formatted using characters other than a
dot as the decimal place can be correctly detected and sorted.

- A large part of the world uses the comma as a decimal place, so it
  makes sense to have this option built-in directly to DataTables,
  rather than needing to use plu-in sorting types as before:
  http://en.wikipedia.org/wiki/Decimal_mark

- However, the decimal place character cannot be detected automatically
  since there are far to many ambiguities. As such, a new
  `language.decimal` option is defined which is passed through to the
  type detection functions. The type detection functions can then use
  that character to alter their detection functions to transform numbers
  into the dot formatted equivilent for parsing in Javascript.

- The numeric sorting methods have been bundled together in the function
  `_addNumericSort` which is called when a character is given for the
  decimal mark, adding the sorting functions required specifically for
  that mark. This means that any character at all can be added, while
  keeping the table's sort performance as it was.

- Code size in increased a little for this new feature, but a lot of
  work has been done to keep it to a minimum (while still optimising for
  the most common use case of a dot decimal place), and this is a good
  feature to have in DataTables' core code.

- All required documentation added and updated.

- Special thanks to Tobias Bäthge for suggesting and sponsoring this
  feature.

<h1>DataTables example <span>- Deferred rendering for speed</span></h1>
<div class="info">
<p>When working with large data sources, you might seek to improve the speed at which DataTables runs.
One method to do this is to make use of the built-in deferred rendering option in DataTables with the
<a href="//datatables.net/reference/option/deferRender"><code class="option" title=
"Initialisation option">deferRender</code></a> option.</p>
<p>When deferred rendering is enabled, rather than having DataTables create all <code class="tag"
title="HTML tag">TR</code> and <code class="tag" title="HTML tag">TD</code> nodes required for the
table when the data is loaded, DataTables will only create the nodes required for each individual row
at the time of that row being drawn on the page (these nodes are then retained in case they are needed
again so they aren't created multiple times). This can give a significant performance increase, since a
lot less work is done at initialisation time.</p>
<p>The example below shows DataTables with deferred rendering enabled. For this small example you'll
likely notice no difference, but larger tables can benefit significantly from simply enabling this
parameter.</p>
</div>
<table id="example" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Name</th>
<th>Position</th>
<th>Office</th>
<th>Extn.</th>
<th>Start date</th>
<th>Salary</th>

<p>The Javascript shown below is used to initialise the table shown in this

$('#example').dataTable( {
&quot;ajax&quot;: &quot;data/arrays.txt&quot;,
&quot;deferRender&quot;: true

<p>In addition to the above code, the following Javascript library files are loaded for use in this
example:</p>

<li><a href="../../media/js/jquery.dataTables.js">../../media/js/jquery.dataTables.js</a></li>

<div class="css">

<p>This example uses a little bit of additional CSS beyond what is loaded from the library
files (below), in order to correctly display the table. The additional CSS used is shown
below:</p><code class="multiline brush: js;"></code>

<p>The following CSS library files are loaded for use in this example to provide the styling of the

will update automatically as any additional data is loaded.</p>

that this is just an example script using PHP. Server-side processing scripts can be written in any
