Allan Jardine 60745afb14 New: Bootstrap 4 integration with DataTables
- Bootstrap 4 is currently in beta so things can, and probably will
  still change. Bootstrap 4 packages for DataTables won't be made
  available until at least a beta release of Bootstrap 4.
- A few things have changed in Bootstrap 4 and rather than trying to
  make the exisiting Bootstrap files work for both BS3 and BS4 it makes
  sense to offer both. We'd need to detect which version of BS is loaded
  and that can be quite unreliable (and delayed since the body would
  need to be available).
- Pagingation requires a couple of classes, but no change in structure
- BS4 don't include icons any more, so need to use UTF8 arrows to show
  sorting (don't particularly want other dependencies, although it is
  easy to add with CSS if you want more icon control)
- Outstanding issue: The select element for paging control is not of a
  consistent height with the search input. This appears to be a
  Bootstrap issue: https://github.com/twbs/bootstrap/issues/17194

<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</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</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</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()</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</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 data = table.row( $(this).parents('tr') ).data();
alert( data[0] +&quot;'s salary is: &quot;+ 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="//code.jquery.com/jquery-1.12.0.min.js">//code.jquery.com/jquery-1.12.0.min.js</a>

<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>
