DataTable（jQuery）删除最后一个孩子

Question

I have the following question: I have a DataTable(jQuery) that I order by the first column descending. What I'm trying to do is to remove the last row if the count (Ex. 10) has been reached so the table will never exceed 10 rows. I have tried a few ways all with no success. Any help would be appreciated.

UPDATE: For some reason it only removes the first row.

    // This is where I assign the DataTable to a variable.
    var unprintedTable = $('#unprinted-table').DataTable({
           "order": [
               [1, "desc"]
           ]
    });

    var unprintedLogLength = 5;
    var unprintedLogCount = 0; // Incremented when a new row is added.

    if (unprintedLogCount > unprintedLogLength) {
        unprintedTable.row($(this).parent('tr:last-child')[0]).remove();
    }

  <button onclick="RemoveLastRow()">Remove Last Row</button>
    <table id="MyTable" class="table table-bordered table-striped" width="100%" cellspacing="0">
        <thead>
            <tr>
                <th>Column 1</th>
                <th>Column 2</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td><button class="Mybtn">Click me</button></td>
                <td>Hello</td>
            </tr>
        </tbody>
    </table>

    <script>
        var Dtable;
        $(document).ready(function () {
            Dtable = $("#MyTable").DataTable();
        });


        function RemoveLastRow() {
            Dtable.row(Dtable.data().length).remove().draw(false);         
         );
    </script>
