<h1>DataTables example <span>Generated content for a column</span></h1>
<div class="info">
<p>In some tables you might wish to have some content generated automatically. This can be done in a number of ways:</p>
<ul class="markdown">
<li><a href="//datatables.net/reference/option/columns.render"><code class="option" title=
"DataTables initialisation option">columns.render<span>DT</span></code></a> for content that is dynamic (i.e. based upon the row's data)</li>
<li><a href="//datatables.net/reference/option/columns.defaultContent"><code class="option" title=
"DataTables initialisation option">columns.defaultContent<span>DT</span></code></a> for static content (i.e. simple strings)</li>
</ul>
<p>This examples shows the use of <a href="//datatables.net/reference/option/columns.defaultContent"><code class="option" title=
"DataTables initialisation option">columns.defaultContent<span>DT</span></code></a> to create a <em>button</em> element in the last column of the table. A simple
jQuery <code>click</code> event listener is used to watch for clicks on the row, and when activated uses the <a href=
"//datatables.net/reference/api/row().data()"><code class="api" title="DataTables API method">row().data()<span>DT</span></code></a> method to get the data for the
row and show a bit of information about it in an <code>alert</code> box. This is a simple use case, but it can be built up to be arbitrarily complex.</p>
<p>Note also that the <a href="//datatables.net/reference/option/columns.data"><code class="option" title=
"DataTables initialisation option">columns.data<span>DT</span></code></a> option for the column has been set to <code>null</code> to indicate that the column has
no information that should be obtained data source object.</p>

<p>The Javascript shown below is used to initialise the table shown in this example:</p><code class="multiline language-js">$(document).ready(function() {
var table = $('#example').DataTable( {

var data = table.row( $(this).parents('tr') ).data();
alert( data[0] +"'s salary is: "+ data[ 5 ] );
} );
} );</code>
<p>In addition to the above code, the following Javascript library files are loaded for use in this example:</p>
<ul>
<li><a href="../../media/js/jquery.js">../../media/js/jquery.js</a></li>
<li><a href="../../media/js/jquery.dataTables.js">../../media/js/jquery.dataTables.js</a></li>

<div class="table">
<p>The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:</p>
</div>
<div class="css">
<div>
<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 language-css"></code>
</div>
<p>The following CSS library files are loaded for use in this example to provide the styling of the table:</p>
<ul>
<li><a href="../../media/css/jquery.dataTables.css">../../media/css/jquery.dataTables.css</a></li>
</ul>
</div>
<div class="ajax">
<p>This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is
loaded.</p>

<p>The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side
