How to prevent a JButton in a Table Cell from stretching its size.

Question

Hi,
I have JButton added to a Table Cell. But the button is filled up by covering the whole area of the cell and when I go for increase the width of the Table column, the button size is also stretched up along with the column's increasing width. How can I implement a solutiong so that I have a preferred size for the button so that when I go for stretch the column, the button should retain its preferred size. That mean it should not be stretched.
I hereby added the code for a reference,
    // ButtonEditor
    class ButtonEditor extends DefaultCellEditor {
        private static final long serialVersionUID = 42L;
         private String    label;
         private boolean   isPushed;
                protected JButton button;
         public ButtonEditor(JCheckBox checkBox) {
              super(checkBox);
              button = new JButton();
              button.setOpaque(true);
              button.addActionListener(new ActionListener() {
                   public void actionPerformed(ActionEvent e) {
                        fireEditingStopped();
          * Override the DefaultCellEditor inbuilt method
         public Component getTableCellEditorComponent(JTable table, Object value,
                   boolean isSelected, int row, int column) {
              if(value.equals(AdminToolsRes.resBundle.getString("nei.label.blockSync"))){
                   label = (value == null) ? "" : value.toString();
                   button.setText( label );
                   isPushed = true;
                   return button;
              else
                   return null;
          * Stop cell editing
         public boolean stopCellEditing() {
              isPushed = false;
              return super.stopCellEditing();
          * call the fireEditingStopped method
         protected void fireEditingStopped() {
              super.fireEditingStopped();
          * sets the cell editable to True
          * @return
         public boolean isCellEditable(){
              return true;
    //ButtonRenderer
    class ButtonRenderer extends JButton implements TableCellRenderer {
        private static final long serialVersionUID = 42L;
         public ButtonRenderer() {
              setOpaque(true);
          * Override the TableCellRenderer inbuilt method
         public Component getTableCellRendererComponent(JTable table, Object value,
                   boolean isSelected, boolean hasFocus, int row, int column) {
              if (isSelected) {
                 setBackground(table.getSelectionBackground());
             } else{
                 setForeground(table.getForeground());
                 setBackground(table.getBackground());
              if(value.equals(AdminToolsRes.resBundle.getString("nei.label.blockSync"))){
                   setText( (value == null) ? "" : value.toString() );
                   return this;
              }else{
                   JTextField txtFld = new JTextField();
                   txtFld.setBorder(null);
                   txtFld.setText((value ==null) ? "" : value.toString());
                   if(isSelected){
                        txtFld.setForeground(table.getSelectionForeground());
                        txtFld.setBackground(table.getSelectionBackground());
                   return txtFld;
    }Please help me in answering the question.

I feel, here the JPanel also might get stretched up.All renderers are sized to fill the entire area of the cell, so yes, the panel will get stretched, but the button won't. That is why the suggestion was made.

Not sure, but you might be able to override the JTable.prepareRenderer(...) method to reset the size of the button back to is preferred size. I have no idea how this will affect the rendering.
