a column of datatables is hidden automatically

Kospi

Hello everybody!,
I don't understand because datatables is hidden a column, when I only changed a path to an image.
I attached two images, before the change and after change.

This is the code:

  $('#tmovimiento').dataTable({
                    ajax: {
                        method: "POST",
                        url: "${pageContext.request.contextPath}/privado/Control?accion=Grid&modo=1",
                        dataSrc: "datos"
                    },
                    language: {
                        url: "https://cdn.datatables.net/plug-ins/1.10.16/i18n/Spanish.json"
                    },
                    columns: [
                        {data: "foto", orderable: false,
                            render: function (data, type, row) {
                                var linea = '<img src=http://localhost:8080/${sessionScope.rCorFotos}' + data + ' width="120">';
                                return linea;
                            }
                        },
                        {data: "descrip", orderable: true},
                        {data: "precio", orderable: false,
                            render: function (data, type, row) {
                                return '$ ' + data;
                            }
                        },
                        {data: "acciones", orderable: false}
                    ],
                    order: [[1, 'asc']]
                });

and I only changed the line "var linea", before was equal to :
'var linea = '<img src=fotos/' + data + ' width="120">';'

Any ideas?
I appreciate any help!
thanks in advance.
