html页面只显示表格中的上面几行图片,下拉条也到底了,手动刷新后才能显示出全部图片来,下拉条也变长了?

html页面只显示表格中的上面几行图片,下拉条也到底了,手动刷新后才能显示出全部图片来,下拉条也变长了?

//表格大小就自己调了,我只给出显示的方法

import java.util.Vector;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class TableIco extends JFrame {
private static final long serialVersionUID = 1L;
private ImageIcon la = new ImageIcon(TableIco.class.getResource("1.jpg"));
private ImageIcon lb = new ImageIcon(TableIco.class.getResource("2.jpg"));
private JTable ta = null;
private JScrollPane pan = null;
private DefaultTableModel model = null;

public TableIco() {
this.setBounds(200, 200, 400, 300);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
model = new IconModel(new Object[][] , },
new Object[] );
ta = new JTable(model);
pan = new JScrollPane(ta);
this.getContentPane().add(pan);
this.setVisible(true);

}

public static void main(String[] args) {
new TableIco();
}

}

class IconModel extends DefaultTableModel {
private static final long serialVersionUID = 1L;

public IconModel(Object[] cnames, int row) {
super(cnames, row);
}

public IconModel(Object[][] data, Object[] columnNames) {
super(data, columnNames);
}
//important here
public Class getColumnClass(int col) {
Vector v = (Vector) dataVector.elementAt(0);
return v.elementAt(col).getClass();
}

public boolean isCellEditable(int row, int col) {
Class columnClass = getColumnClass(col);
return columnClass != ImageIcon.class;
}
}

我不会~~~但还是要微笑~~~：）
