copied!<p>The problem lies with your TableModel, you have to tell the table that it has to render an image in that column overriding the <code>getColumnClass(int column)</code> method of the model.</p> <p>Look at this <a href="https://stackoverflow.com/a/4947154/2588463">answer</a> by camickr.</p> <p><strong>UPDATE</strong></p> <p>Minimal example of a JTable with an ImageIcon using DefaultTableModel's renderer to paint it. I borrowed the <code>updateRowHeights()</code> code from <a href="https://stackoverflow.com/a/1784601/2588463">this answer</a> again by camickr, without it the icon was bigger than the row and wasn't fully displayed.</p> <p>The important thing here is that now when the renderer calls <code>getColumnClass(1)</code>, it gets <code>ImageIcon.class</code> so the code to render icons will be executed. By default this method would return <code>Object.class</code> and the renderer would ignore the fact that it's an icon.</p> <pre><code>import java.awt.BorderLayout; import java.awt.Component; import javax.swing.ImageIcon; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.SwingUtilities; import javax.swing.table.DefaultTableModel; public class ImageIconTable { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new ImageIconTable().initGUI(); } }); } public void initGUI() { JFrame frame = new JFrame(); DefaultTableModel tableModel = new DefaultTableModel() { @Override public Class getColumnClass(int column) { if (column == 1) return ImageIcon.class; return Object.class; } }; tableModel.addColumn("Row 1"); tableModel.addColumn("Icons Row"); tableModel.addRow(new Object[]{"This cell is an Object", new ImageIcon("icon.jpg")}); _table = new JTable(tableModel); updateRowHeights(); frame.add(new JScrollPane(_table), BorderLayout.CENTER); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); frame.pack(); frame.setVisible(true); } private void updateRowHeights() { try { for (int row = 0; row < _table.getRowCount(); row++) { int rowHeight = _table.getRowHeight(); for (int column = 0; column < _table.getColumnCount(); column++) { Component comp = _table.prepareRenderer(_table.getCellRenderer(row, column), row, column); rowHeight = Math.max(rowHeight, comp.getPreferredSize().height); } _table.setRowHeight(row, rowHeight); } } catch(ClassCastException e) {} } private JTable _table; } </code></pre> <p>It looks like this:</p> <p><img src="https://i.stack.imgur.com/dZgZt.png" alt="Table displaying an icon"></p>
