Answer 1

The appearance of the default table header for a typical Look & Feel is provided by an instance of sun.swing.table.DefaultTableCellHeaderRenderer. You can obtain a copy as follows:

class HeaderRenderer implements TableCellRenderer {

    TableCellRenderer renderer;

    public HeaderRenderer(JTable table) {
        renderer = table.getTableHeader().getDefaultRenderer();
    }

    @Override
    public Component getTableCellRendererComponent(
        JTable table, Object value, boolean isSelected,
        boolean hasFocus, int row, int col) {
        return renderer.getTableCellRendererComponent(
            table, value, isSelected, hasFocus, row, col);
    }
}

and you can install it in the usual way for a given column's type token:

table.setDefaultRenderer(SomeObject.class, new HeaderRenderer(table));
