Table rows not automatically scrolling. Script 1 scrolls, script 2 does not scroll. Why?

I deleted my first question and have rewitten with more detail and addition jSfiddle domos.

I have a script that runs a query and returns data which then populates a table. The rows in the tables auto scroll in a loop. All this works fine and is done by using the following code. However what I need to do is to display the same data from a JSON call enabling automatic screen updates without having to refresh the complete page. I have this working in SCRIPT 2, but what I can't get to work is the automatic scrolling which does work in SCRIPT 1.

SCRIPT 1: THIS WORKS

<table id='table_scroll'>
<section id="section">
do { 
<div class='container'>
    <div class='clientname-text'><?php echo $row_conf['ClientName'];?></div>
    <div class='roomname-text'><?php echo $row_conf['RoomName'];?></div>
    <div class='time-text'><?php echo date("H:i", strtotime($row_conf['RoomFromTime'])) . " - " . date("H:i", strtotime($row_conf['RoomToTime']));?></div>
</div>
} while ($row_conf = mysqli_fetch_assoc($conf));  
</section>
</table>


$.fn.infiniteScrollUp=function(){
    var self=this,conf=self.children()
    setInterval(function(){
    conf.slice(10).hide();
        conf.filter(':hidden').eq(0).slideDown()
        conf.eq(0).slideUp(6000, "linear",function(){
        $(this).appendTo(self);
    conf=self.children();
      });
    },100)
    return this;
}


$(function(){
    $('section').infiniteScrollUp()
})

I now want to use data retuned by a JSON call to dynamically create the table. I have already done this using the following code.

SCRIPT 2 THIS DOES NOT WORK, Can anyone see why?

<table id='table_scroll'>
<section id="section"></section>
</table>

$(document).ready(function() {
    function get_data() {
        $.getJSON("get_data_logos.php", function(json){
            json = json[0].data;
            var tr ;
            $('table').html("");
            for (var i = 0; i < json.length; i++) {
                tr = $('<tr/>');
                tr.css("border-bottom","2px solid #FFF");
                tr.append("<td width='33%'><div class='clientname-text'>" + json[i].ClientName + "</div></td>");
                tr.append("<td width='33%'><div class='roomname-text'>" + json[i].RoomName + "</div></td>");
                tr.append("<td width='33%'><div class='time-text'>" + json[i].RoomFromTime + " - " + json[i].RoomToTime + "</div></td>");
                $('table').append(tr);
            }
        });
    }
get_data();
setInterval(get_data,60000)
});

$.fn.infiniteScrollUp=function(){
    var self=this,conf=self.children()
    setInterval(function(){
    conf.slice(10).hide();
        conf.filter(':hidden').eq(0).slideDown()
        conf.eq(0).slideUp(6000, "linear",function(){
        $(this).appendTo(self);
    conf=self.children();
      });
    },100)
    return this;
}


$(function(){
    $('section').infiniteScrollUp()
})

My question is: How caan I get SCRIPT 2 to work with the scroll as it does in SCRIPT 1.
