First of all about this method:

public Class getColumnClass(int col) {
   return ImageIcon.class;
}

You define data:

final Object[][] data = new Object[][] {
{
  ("qwer"),
  ("qwer"),
  ("qwer"),
  new ImageIcon("C:\\Temp\\b020.gif")}//atr.gif
};

The first columns are String and the last is ImageIcon. But your method always returns ImageIcon.class. That method needs to return the class of the object that each column has. You need to do something like this:

public Class getColumnClass(int col) { 
   if (col==3) return ImageIcon.class; // column 3 has ImageIcon
   return "".getClass(); // the rest are Strings
}

Or better, assuming that data has at least one row:

public Class getColumnClass(int col) { 
   return data[0][col].getClass();
}

Also I noticed that you need to add columns and rows to the table. A simple example on how to add more rows. First you mustn't have data to be an array. You initialize the AbstractTableModel with an array, which is static. Meaning that is difficult to add more rows than the ones already there. If you need to add more rows then you need to make sure that the methods of the AbstractTableModel return those rows. Why don't you try this:

public class CustomTableModel extends AbstractTableModel {
    private String[] columnNames;
    private Vector<Object []> data;

    public CustomTableModel(String[] columnNames, Vector<Object []> data) {
        this.columnNames = columnNames;
        this.data = data;
    }

    public int getRowCount() {
        return data.size();
    }

    public int getColumnCount() {
        return columnNames.length;
    }

    public Object getValueAt(int rowIndex, int columnIndex) {
        Object [] obj = data.get(rowIndex);
        return obj[columnIndex];
    }


    public Class getColumnClass(int columnIndex) {
        Object [] obj = data.get(0);
        return obj[columnIndex].getClass();
    }

    public String getColumnName(int column) {
        return columnNames[column];
    }
    
    [B]public void addRow(Object [] row) {
        data.add(row);
    }[/B]
}

And call it like this:

String [] columnNames = {"Name", "Something", "Image"};
        
        Vector<Object []> data = new Vector<Object []>();

        Object [] v = {"AAAA", "BBBBBB",  icon};
        data.add(v); // first row
        
        
        // create table        
        CustomTableModel ctm = new CustomTableModel(columnNames, data);
        JTable table = new JTable(ctm);

And whenever you need to add a new row just call the add method of the "ctm". That would mean of course that ctm must be visible where you add the new row. You need to add the row at the "ctm" you used to create the table

thank you lot...

here i got your point...

but still i don't know the icon not appearing in cell

if it is appear then i need it be moving(like ring rotating..) not in idle...

please help for me..

Are you saying that the image appears but is not moving? If yes, can you attach it so I can do some tests with it?

[musthafa.aj]

take this gif and test it...

[javaAddict]

I did some testings and when the gif is static then it displays correctly. I had a problem displaying the gif when it has motion. The image displays in the jTable, but it is not moving and when you click the cell then it changes what it displays, but it doesn't have motion. Meaning that every time I clicked another cell and then the image, the image changed what it displayed but it was not moving like it was in your post.

I tried putting it in a JLabel and simply display the label somewhere in the jPanel, outside the table and it was OK.

So 3 Solutions:
1) Use static images and put them in the table

2) Don't use table if you don't have to. You can use GridBagLayout that allows you to put components (buttons, fields, labels) organized and have one of these to be a JLabel with the moving image. Meaning that with the GridBagLayout you will place your components on the jPanel to look like they are in a table

3) Don't listen to me. Just because I couldn't do it, doesn't mean it can be done. Try to search a bit more and find how to put moving images in a table.

And one last general suggestion.

The RecordShow class you created wasn't suppose to do anything but extend the AbstractTableModel. The idea was to do only that and call it from another class. Don't mix things together. RecordShow should extend the AbstractTableModel and only.
Then create another class for the frame.

Speaking of which I find it better to have the class extend the JFrame instead of declaring it in the main. In the constructor put all that code that you used to add components to the frame.
I also added a JLabel just to show you how the moving image works

package stam.bar.dani.tableimages;

import java.awt.BorderLayout;
import java.awt.Color;

import java.awt.Image;

import java.awt.Toolkit;

import java.util.Vector;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;

public class CustomFrame extends JFrame {
    private RecordShow ctm = null;
    private JTable table = null;
    private JScrollPane scrollPane = null;
    private JPanel mainPanel = null;
    
    public CustomFrame(String[] columnNames, Vector<Object []> data) {
        super("Simple Table Example");
        setSize(400,300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        // initialize the components
        ctm = new RecordShow(columnNames, data);
        table = new JTable(ctm);
        scrollPane= new JScrollPane(table);//ScrollPane

        mainPanel=new JPanel();
        mainPanel.setLayout(new BorderLayout());
        mainPanel.add("Center",scrollPane);

        // for testing the image
        mainPanel.add("South",new JLabel(new ImageIcon("C:\\temp\\b020.gif")));

        mainPanel.setBackground(Color.white);
        
        table.getParent().setBackground(Color.black);
        
        getContentPane().add(mainPanel);
        
        // you can leave that and put it where you create the JFrame
        // setVisible(true);
    }
    
    public static void main(String [] args) {
        String [] columnNames = {"Name", "Something", "Image"};
        
        // THE FOLLOWING DATA COULD BE TAKEN FROM ANOTHER METHOD
        // ONE THAT READS A FILE OR A DATABASE
        ImageIcon ii = new ImageIcon("C:\\temp\\b020.gif");
        Vector<Object []> data = new Vector<Object []>();
        Object [] v = {"AAAA", "BBBBBB",  ii};
        data.add(v); // first row
        // <<
        
        // >>
        CustomFrame frame = new CustomFrame(columnNames, data);
        
        // You can call also that method from the constructor. It's up to you
        frame.setVisible(true);
    }
}

Also if the cell where the image is displayed seems to small you can do this, after you initialized the table:

table = new JTable(ctm);
        for (int row=0;row<table.getRowCount();row++) {
            ImageIcon ii = (ImageIcon)table.getValueAt(row, 2);
            table.setRowHeight(row, ii.getIconHeight());
        }

ok thanks lot for you ....

i leave it because the estimation time was expired...

but now i need how do change color of particular row in jtable...

first i show all records in jtable ...

after i process(read from it and insert into DB) one record at a time..

while processing i need that particular row in yellow color...

if the row completed (inserted in DB) THEN the row become GREEN..

HOW TO DO...I TRIED SOME SOLUTION ...BUT IT WILL MAKE WHOLE TABLE AT A TIME...
