如何在UITableView中获得动态调整大小的节标题的高度？

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    // 在这里计算并返回节标题的高度
    return calculatedHeight
}

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    let headerText = // 获取节标题的文本
    let font = // 设置节标题的字体
    let maxSize = CGSize(width: tableView.bounds.width, height: .greatestFiniteMagnitude)
    let options = NSStringDrawingOptions.usesFontLeading.union(.usesLineFragmentOrigin)
    let attributes = [NSAttributedString.Key.font: font]
    
    let boundingRect = headerText.boundingRect(with: maxSize, options: options, attributes: attributes, context: nil)
    let calculatedHeight = ceil(boundingRect.height)
    
    return calculatedHeight
}
