Question

sir
i carefully read the swing tutorial for JTable for the purpose
of rendring specially header rendring.
first u see the code
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
import javax.swing.border.*;
import java.util.*;
import javax.swing.table.*;
public class Myscrollpane extends JScrollPane {
ImageIcon icon=new ImageIcon("images/beach1.jpg");
Image img;
int w,h,wi,hi;
TableColumn column = null;
String[] names = {"Company Code", "Company Name"};
DefaultTableModel model=new DefaultTableModel(names,0);
JTable table=new JTable(model);
LogoViewport vp;//user class extends with JViewport
Myscrollpane(int width,int height){
vp= new LogoViewport(width,height);
setOpaque(false);
setMinimumSize(new Dimension(width,height));
setPreferredSize(new Dimension(width,height));
setSize(350,125);
///////////here r the table methods tocontrol /////////////////////
table.setPreferredScrollableViewportSize(new Dimension width,height));
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF );
table.getTableHeader().setReorderingAllowed(false);
table.setBackground(new Color(245,235,237));
table.setForeground(Color.black);
table.setOpaque(true);
table.setEnabled(false);
table.setFont(new java.awt.Font("Dialog", Font.ITALIC, 12));
table.setGridColor(Color.pink);
table.setRowHeight(22);
table.setSelectionBackground(Color.lightGray);
DefaultTableCellRenderer renderer=new DefaultTableCellRenderer();
TableColumn code=table.getColumnModel().getColumn(0);
renderer.setBackground(Color.red);
//if i use the setIcon method then the data comes from the database is
//not shown because the icon paint above the data.Iwant to paint the
//image on the table dynamically means as table populated the image is
//paint on the table means no fix no of rows.How can i
//do.
code.setCellRenderer(renderer);
TableCellRenderer headerRenderer = table.getTableHeade.().getDefaultRenderer();
TableColumn column1=null;
//i use this to change the color and paste icon of header column
//but it is not work
for (int j = 0; j < 2; j++) {
column1 = table.getColumnModel().getColumn(j);
Component comp = headerRenderer.getTableCellRendererComponent(null, column1.getHeaderValue(), false, false, 0, 0);
comp.setBackground(Color.red);
comp.setIcon(new ImageIcon("myimage.gif")); }
//if i use following it also not work
TableCellRenderer headerRenderer = table.getTableHeader().getDefaultRenderer();
if (headerRenderer instanceof DefaultTableCellRenderer) {((DefaultTableCellRenderer)headerRenderer).setBackground(Color.red);} vp.setView(table);
this.setViewport(vp);
}plz help me with the code.
stated as above i also want to draw the image on the table with the use of DefaultTabel
Model and data set from the data base.Initally no row is shown.
