Laravel error Unauthenticated when passing Datatable from view to controller

Hello i'm trying to pass Datatable from view to my controller. Here is my Datatable code in view :

<div class="table-responsive">
        <table id="example1" class="table table-bordered table-hover display">
                 <thead>
                       <tr>
                            <th><input type="checkbox" name="select_all" value="1" id="example-select-all"></th>
                             <th>No</th>
                             <th>Id</th>
                             <th>Exemplar</th>
                             <th width="40%">Title</th>
                       </tr>
                    </thead>
                    <tbody id="bookTable">
                    </tbody>
        </table></div>

And here is my javascript code :

$('#printLabel').click(function(e){
                e.preventDefault();
                 $.post("", 
                 //$('#searchForm').serialize())
                 table1.$('input,select,textarea').serialize())
                            .fail(function(data) {
                                alert(data.responseJSON.error);
                            });

                });

The codes above gave me error : {error: "Unauthenticated."}. Also, i'm not sure if "table1.$('input,select,textarea').serialize())" is the right why to pass datatable to controller.
