However, cookies have a number of disadvantagies such as requiring increased HTTP bandwidth and a 4K limit. The W3C Web Storage specification defines <a href="https://developer.mozilla.org/en/DOM/Storage">localStorage</a> as a local storage method which we can use in DataTables to store state without the inherent issues in using cookies.</p> <p>This example shows the use of <i>fnStateSave</i> and <i>fnStateLoad</i> to very simply store the table state in localStorage and then load it back again when needed.</p> <h1>Live example</h1> <div id="demo"> <table cellpadding="0" cellspacing="0" border="0" class="display" id="example"> <thead> <tr> <th>Rendering engine</th> <th>Browser</th>
