TableCellRenderer for a JTableCell contains imageIcon

Question

Hi, all.
I am writing a TableCellRenderer for a column in JTable which contains imageIcon. It sets the background of the cell to a specific color. It worked fine when the column's datatype is string. But when the datatype of the cell is an imageIcon, the setBackground method somehow overlaps the imageIcon, basically, I can't see the image Icon anymore. As I understand, while the datatype is imageIcon, the JTable basically Centers the imageIcon on a JLabel, then when I set the background of JLabel to a color, it should work, right? Here is the code, any help would be greately appreciated.
<pre>
package org.anser.newshound.gui;
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
import java.util.*;
import java.io.*;
public class TableCellRendererForThumbnailTable extends DefaultTableCellRenderer
public static final Color DELETE_COLOR = Color.red;
public static final Color NULL_COLOR = Color.white;
private int[] rowStatus;
public TableCellRendererForThumbnailTable(int[] rowStatus){
super();
this.rowStatus = rowStatus;
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column){
JLabel c = (JLabel) super.getTableCellRendererComponent(table,
value,
isSelected,
hasFocus,
row,
column);
c.setOpaque(true);
if ( rowStatus[row] != -1 ) {
if ( rowStatus[row] == ThumbAndMetaResultViewer.ACTION_DELETE ){
c.setBackground( DELETE_COLOR );
c.setForeground( Color.black );
else {
c.setBackground( NULL_COLOR );
c.setForeground( Color.black);
return c;

I don't see that you are calling setIcon anywhere in the code - you need to make a change:
c.setOpaque(true);
// Add this  ------------8<-----------
if (value instanceof Icon)
    c.setIcon((Icon) value);
// ---------------------8=-----------
if ( rowStatus[row] != -1 ) {
