我最喜欢的自动完成jcombobox/jtextfield没有问题，仍然有第二选择的用途 AutoComplete JTextField 而不是 AutoComplete JComboBox ,

试试这个

JTable table = new JTable(data, columns);
    table.putClientProperty("terminateEditOnFocusLost", true);
    JScrollPane scrollPane = new JScrollPane(table);
    final JXComboBox editorComboBox = new JXComboBox(array);
    editorComboBox.addAncestorListener(new AncestorListener() {
        public void ancestorAdded(AncestorEvent event) {
            //make sure combobox handles key events
            editorComboBox.requestFocusInWindow();
        }
        public void ancestorMoved(AncestorEvent event) {}
        public void ancestorRemoved(AncestorEvent event) {}
    });
    AutoCompleteDecorator.decorate(editorComboBox);
    TableColumn column = table.getColumnModel().getColumn(0);
    column.setCellEditor(new ComboBoxCellEditor(editorComboBox));
