Any idea, whats wrong with my code? The items are not shown as expected...

{:fx/type :table-view
                                          :columns [{:fx/type :table-column
                                                     :text "Hello"
                                                     :sortable false}
                                                    {:fx/type :table-column
                                                     :text "World"}]
                                          :items [["How" "are"]
                                                  ["ya" "?"]]}
