java - JavaFX - how can I get a TableView to show the strings in an array? -

after trying many different ways, have not been able tableview display strings. originally, info supposed come resultset object but, not work. latest effort (below) seems straightforward way display info but, strings still not show.

as can see, tableview , listview described in fxml document. listview shows it's strings without problems. missing something?
