我正在尝试在 JTable 中添加行，它在我身上运行良好，问题是当我尝试单击 JTable 中的单元格时，出现错误提示ArrayIndexOutOfBoundsException: -1。有人可以帮我吗？ 
          PreparedStatement pr = conn.prepareStatement("SELECT * FROM tblInfo");
        ResultSet rs = pr.executeQuery();
        
        ResultSetMetaData metadata = rs.getMetaData();
        
        Vector<String> col = new Vector<String>();
        int columnCount = metadata.getColumnCount();
        
        for(int i=1; i<=columnCount; i++)
        {
        col.add(metadata.getColumnName(i));
        } 
            
        Vector<Vector<Object>> data = new Vector<Vector<Object>>();
        while(rs.next())
        {
            Vector<Object> vector = new Vector<Object>();
            for(int i=1; i<=columnCount; i++)
            {
                vector.add(rs.getObject(i));
            }
            data.add(vector);
        }
            
    
        table = new JTable(data, col);
        table.setBackground(Color.LIGHT_GRAY);
        table.setForeground(Color.white);
        table.setFont(new Font("Ubuntu Light", Font.PLAIN, 16));
        table.setAutoResizeMode(table.AUTO_RESIZE_ALL_COLUMNS);
        table.setRowHeight(22);
        table.setCellSelectionEnabled(false);
        
        
        table.addMouseListener(new MouseAdapter(){
            public void mouseClicked(MouseEvent m){
                
                Object one, two, three, four;
                int i = table.getSelectedRow();
                
                int col = table.getSelectedColumn();
                int row = table.getSelectedRow();
                one = GetData(table,i, 0);
                two = GetData(table,i, 1);
                
                txtDoctorID.setText(one.toString());
                txtDoctorName.setText(two.toString());   
                
            //  txtDoctorID.setText(table.getModel().getValueAt(row,col).toString());   
            
                
                                            
            }
        }); 
        
        
        scroll = new JScrollPane(this.table);
        scroll.setSize(680,200);
        scroll.setLocation(265,65);
        scroll.setBackground(Color.LIGHT_GRAY);
        scroll.setAutoscrolls(true);
        scroll.setWheelScrollingEnabled(true);
        getContentPane().add(scroll); 
            
        st.close();
        rs.close();

// 我刚刚删除了 try 和 catch

这里是错误提示
