Answer 1

extends the defaultcellrenderer make it return a Jbutton as the component to draw.
class OverCellRendererClass extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column) {
//put your stuff here to make or get a button
return myButton;
Use something like this to set the renderer for the column :
tb.getColumnModel().getColumn(4).setCellRenderer(new YourCellRendererClass());
