我可以在UITableView中自定义节标题吗？(字体,图片......)

func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String {
    let font = UIFont.systemFont(ofSize: 16)
    let color = UIColor.blue
    return String(format: "%d. %@", section + 1, color.description)
}

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.width, height: 40))
    headerView.backgroundColor = UIColor.yellow
    
    let label = UILabel(frame: CGRect(x: 10, y: 10, width: headerView.bounds.width - 20, height: 20))
    label.text = "Section \(section)"
    label.textColor = UIColor.black
    headerView.addSubview(label)

    return headerView
}
