997: Mainline

The easiest way to change the way that cells are rendered is to create a subclass of a JComponent subclass that implements the TableCellRenderer interface.

The following table-cell renderer, for example, uses and reuses a single, white-background, appropriately right or left-aligned, borderless JLabel instance:

import java.awt.*; 
import javax.swing.*; 
import javax.swing.table.*; 
public class MovieTableCellRenderer extends JLabel 
                                    implements TableCellRenderer { 
 public Component getTableCellRendererComponent( 
   JTable table, Object value, boolean isSelected, 
   boolean hasFocus, int row, int column) { 
  setText(value.toString()); 
  setOpaque(true); 
  setBackground(Color.white); 
  if (value instanceof Integer) { 
   setHorizontalAlignment(SwingConstants.RIGHT); 
  } 
  else if (value instanceof String) { 
   setHorizontalAlignment(SwingConstants.LEFT); 
  } 
  return this; 
 } 
}
