Freeze pane on SharePoint list

In case of a larger SharePoint list, end-users may appreciate that the header row remains in the visible area while they scroll through the list. Out-of-the-box the SharePoint XsltListView webpart does not provide this functionality. However, it is possible to augment the standard behavior by modifying the rendered HTML through javascript. There are multiple examples published, but for some reason these did not immediate work for me. Did get me inspired though, and I coded a jQuery-snippet that when inserted in a page containing a XsltListView webpart delivers the 'freeze pane':

<script src="https://code.jquery.com/jquery-1.11.2.min.js" type="text/javascript"></script>
<script type="text/javascript">

$(document).ready(function () {
    var $table = $(".ms-listviewtable").first().data("summary", "<listview name>");

    // WRAP TABLE IN SCROLL PANE
    $("#s4-workspace").css( { overflow: 'hidden' } );
    $table.wrap("<DIV class='FreezedLV' style='OVERFLOW: auto; HEIGHT: 550px;'></DIV>");

    // FROZEN HEADER ROW
    $(".FreezedLV").wrap("<DIV class='FreezedLVContainer'></DIV>");
    $("<table id='FreezedTR' class='ms-listviewtable' cellPadding='1' cellSpacing='0'></table>").
        insertBefore(".FreezedLV");
    $("#FreezedTR").width($table.width() + "px");

    var $origHeader = $("TR.ms-viewheadertr:first", $table);
    var $firstRowTable = $("TR.ms-itmhover:first", $table);
    var $freezeHeader = $origHeader.clone();
    // Propagate the computed width of columns of origheader to freezeheader
    $origHeader.children("th").each(function() {
        var width = $(this).width();
        var ownerIndex = $(this).index();
        $($freezeHeader.children("th")[ownerIndex]).width(width + "px");
    });

    // Propagate the implicit width of row columns as explicit widths in first row to 
    // avoid layout-changes when hiding the original header
    $firstRowTable.children("td").each(function() {
        var width = $(this).width();
        var ownerIndex = $(this).index();        
        $($firstRowTable.children("td")[ownerIndex]).width(width + "px");        
    });

    $("#FreezedTR").append($freezeHeader);
    $origHeader.hide();
});

</script>
