我是JavaFX的新手，我只想尝试从CSV文本文件填充FXML中定义的tableview。我的代码如下：
package student;
import java.net.URL;
import java.util.*;
import javafx.fxml.*;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;

public class StudInfoController implements Initializable {

@FXML
private Label rnolbl;
@FXML
private Label maillbl;

@FXML
private Label altlbl;
@FXML
private Tab exams;
@FXML
private Tab result;
@FXML
private TableView<Exam> ExamTable;
@FXML
private TableView<Result> ResultTable;
@FXML
private TableColumn<Exam, String> eSub;
@FXML
private TableColumn<Exam, String> eDate;

@FXML
private TableColumn<Result, String> rTE;
@FXML
private TableColumn<Result, String> rMarks;
/**

}
private List<Exam> InsertExam() {
try {
FileRead fr = new FileRead();
String[] l = fr.examRead();
String[] items;
int i = 0;

}
}

FXML代码如下：
