在使用带有从文件读取的项目列表的自定义TableModel时，如何更新jtable

import javax.swing.JTable;
import javax.swing.table.AbstractTableModel;
import java.util.List;

public class ProjectTableModel extends AbstractTableModel {
    private List<Project> projects;
    private String[] columnNames = {"项目名称", "项目描述"};

    public ProjectTableModel(List<Project> projects) {
        this.projects = projects;
    }

    public void updateData(List<Project> projects) {
        this.projects = projects;
        fireTableDataChanged();
    }

    @Override
    public int getRowCount() {
        return projects.size();
    }

    @Override
    public int getColumnCount() {
        return columnNames.length;
    }

    @Override
    public Object getValueAt(int rowIndex, int columnIndex) {
        Project project = projects.get(rowIndex);
        if (columnIndex == 0) {
            return project.getName();
        } else if (columnIndex == 1) {
            return project.getDescription();
        }
        return null;
    }

    @Override
    public String getColumnName(int column) {
        return columnNames[column];
    }
}

// 在主程序中使用自定义的TableModel和JTable
public class Main {
    public static void main(String[] args) {
        List<Project> projects = readProjectsFromFile(); // 从文件读取项目列表
        ProjectTableModel model = new ProjectTableModel(projects);
        JTable table = new JTable(model);
        // 将table添加到界面中的合适位置
    }
}
