IE8 issues(Responsive & colReorder & Order)

tate

Two issues will occur if you have set the Responsive & colReorder & Order in IE8.

$(document).ready(function() {
    $('#example').DataTable( {
        colReorder: true,
        responsive: true
    } );
} );

1.Header of the arrow is not reflected at the time of the order
https://www.datatables.net/forums/discussion/30750/ie8-responsive-issues
Added code that has been described in the link .
2.Arrow is not reflected at the time of the order after the Drag
We changed the coding as shown below
_fnCreateDragNode

    var clonedTable  = $( origThead ).clone( false ).empty()[0];
    var clonedThead = $( origThead ).clone( false ).empty().appendTo( clonedTable );
    var clonedTr   = $( origTr ).clone( false ).empty().appendTo( clonedTable );
    this.dom.drag = $(clonedTable)
        .addClass( 'DTCR_clonedTable' )
        .append(
            $(clonedThead).append(
                $(clonedTr).append(
                    cloneCell[0]
                )
            )
        )
        .css( {
            position: 'absolute',
            top: 0,
            left: 0,
            width: $(origCell).outerWidth(),
            height: $(origCell).outerHeight()
        } )
        .appendTo( 'body' );

I think it is a bad way to change the datatables.js
Do you have any sugesstions?
