Is it possible to allow a user to select rows and copy from a TableView?

Answer 1

tableView.getSelectionModel().setCellSelectionEnabled(true);
tableView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);

MenuItem item = new MenuItem("Copy");
item.setOnAction(new EventHandler<ActionEvent>() {
    @Override
    public void handle(ActionEvent event) {
        ObservableList<TablePosition> posList = tableView.getSelectionModel().getSelectedCells();
        int old_r = -1;
        StringBuilder clipboardString = new StringBuilder();
        for (TablePosition p : posList) {
            int r = p.getRow();
            int c = p.getColumn();
            Object cell = tableView.getColumns().get(c).getCellData(r);
            if (cell == null)
                cell = "";
            if (old_r == r)
                clipboardString.append('\t');
            else if (old_r != -1)
                clipboardString.append('\n');
            clipboardString.append(cell);
            old_r = r;
        }
        final ClipboardContent content = new ClipboardContent();
        content.putString(clipboardString.toString());
        Clipboard.getSystemClipboard().setContent(content);
    }
});
ContextMenu menu = new ContextMenu();
menu.getItems().add(item);
tableView.setContextMenu(menu);
