import java.awt.Component;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.AbstractTableModel;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableCellRenderer;
import javax.swing.table.TableModel;

public class TableTest {

TableModel dataModel = new AbstractTableModel() {
public int getColumnCount() {
return 1000;
}

public int getRowCount() {
return 1000;
}

public Object getValueAt(int row, int col) {
return new Integer(row * col);
}
};

private JTable table = new JTable(dataModel);

private JScrollPane scrollpane = new JScrollPane(table);

public TableTest() {
JFrame f = new JFrame();
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
table.getColumn("A").setCellRenderer(new ButtonRenderer());
f.getContentPane().add(scrollpane);
f.setVisible(true);
f.pack();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

private class ButtonRenderer extends JButton implements TableCellRenderer {
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column) {
this.setText((value == null) ? null : value.toString());
return this;
}
}

public static void main(String[] args) {
TableTest tt = new TableTest();
}
}

想嵌入什么，就在getTableCellRendererComponent方法里返回什么，getTableCellRendererComponent里还应该加些代码，不然表现不对，比如：Color,border什么的
