TableView自定义单元格

准备数据

StudentProperty student1 = new StudentProperty("鸢一折纸", 20, 80.0, false);  
StudentProperty student2 = new StudentProperty("本条二亚", 21, 90.0, false);  
StudentProperty student3 = new StudentProperty("时崎狂三", 22, 100.0, false);  
StudentProperty student4 = new StudentProperty("冰芽川四糸乃", 23, 70.0, false);  
StudentProperty student5 = new StudentProperty("五河琴里", 24, 60.0, false);  
StudentProperty student6 = new StudentProperty("星宫六喰", 20, 80.0, false);  
StudentProperty student7 = new StudentProperty("镜野七罪", 21, 90.0, false);  
StudentProperty student8 = new StudentProperty("八舞夕弦", 22, 100.0, false);  
StudentProperty student9 = new StudentProperty("八舞耶俱矢", 23, 70.0, false);  
StudentProperty student10 = new StudentProperty("诱宵美九", 24, 60.0, false);  
StudentProperty student11 = new StudentProperty("夜刀神十香", 24, 60.0, false);  
ObservableList<StudentProperty> list = FXCollections.observableArrayList();  
list.addAll(student1, student2, student3, student4, student5, student6, student7, student8, student9, student10, student11);  
// 拷贝可观察列表  
List<StudentProperty> listBackup = new ArrayList<>(list);  
TableView<StudentProperty> tableView = new TableView<>(list);  
tableView.setLayoutX(100);  
tableView.setLayoutY(100);  
tableView.setPrefWidth(500);  
tableView.setPrefHeight(200);  
tableView.setPlaceholder(new Text("None Data"));  
// 选择性显示或隐藏某列
tableView.setTableMenuButtonVisible(true);

为实体类的每个属性创建列

TableColumn<StudentProperty, String> nameCol = new TableColumn<>("姓名");  
nameCol.setCellValueFactory(new PropertyValueFactory<>("name"));  
TableColumn<StudentProperty, Integer> ageCol = new TableColumn<>("年龄");  
ageCol.setCellValueFactory(new PropertyValueFactory<>("age"));  
TableColumn<StudentProperty, Double> scoreCol = new TableColumn<>("充能");  
scoreCol.setCellValueFactory(new PropertyValueFactory<>("score"));  
TableColumn<StudentProperty, Boolean> isBoyCol = new TableColumn<>("性别");  
isBoyCol.setCellValueFactory(new PropertyValueFactory<>("gender"));  
tableView.getColumns().add(nameCol);  
tableView.getColumns().add(ageCol);  
tableView.getColumns().add(scoreCol);  
tableView.getColumns().add(isBoyCol);
// 设置每列宽度相同（列拉长时挤占空间）  
tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

自定义每一列的单元格

姓名列

nameCol.setCellFactory(new Callback<TableColumn<StudentProperty, String>, TableCell<StudentProperty, String>>() {  
    @Override  
    public TableCell<StudentProperty, String> call(TableColumn<StudentProperty, String> param) {  
        return new TableCell<StudentProperty, String>() {  
            String name = null;  
            @Override  
            protected void updateItem(String item, boolean empty) {  
                super.updateItem(item, empty);  
                if (empty || item == null) {  
                    return;  
                }  
                // 设置居中  
                this.setAlignment(Pos.CENTER);  
                name = item;  
                initGraphic();  
            }  
            @Override  
            public void startEdit() {  
                super.startEdit();  
                TextField textField = new TextField(name);  
                this.setGraphic(textField);  
                // 回车提交事件  
                textField.setOnKeyPressed(event -> {  
                    if (event.getCode() == KeyCode.ENTER) {  
                        commitEdit(textField.getText());  
                    }  
                });  
            }  
            @Override  
            public void cancelEdit() {  
                super.cancelEdit();  
                initGraphic();  
            }  
            @Override  
            public void commitEdit(String newValue) {  
                super.commitEdit(newValue);  
                name = newValue;  
            }  
            private void initGraphic() {  
                // 单元格文本居中  
                Label label = new Label(name);  
                this.setGraphic(label);  
            }  
        };  
    }  
});

年龄列

ageCol.setCellFactory(new Callback<TableColumn<StudentProperty, Integer>, TableCell<StudentProperty, Integer>>() {  
    @Override  
    public TableCell<StudentProperty, Integer> call(TableColumn<StudentProperty, Integer> param) {  
        return new TableCell<StudentProperty, Integer>() {  
            Integer age = 0;  
            @Override  
            protected void updateItem(Integer item, boolean empty) {  
                super.updateItem(item, empty);  
                if (empty || item == null) {  
                    return;  
                }  
                this.setAlignment(Pos.CENTER);  
                age = item;  
                initGraphic();  
            }  
            @Override  
            public void startEdit() {  
                super.startEdit();  
                Spinner<Integer> spinner = new Spinner<>(0, 100, age);  
                this.setGraphic(spinner);

            }  
        };  
    }

分数列（不可编辑）

scoreCol.setCellFactory(new Callback<TableColumn<StudentProperty, Double>, TableCell<StudentProperty, Double>>() {  
    @Override

            }  
        };
