如何在启用isEditing的情况下让UITableViewCell停留在底部？

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if tableView.isEditing {
        let lastSectionIndex = tableView.numberOfSections - 1
        let lastRowIndex = tableView.numberOfRows(inSection: lastSectionIndex) - 1
        if indexPath.section == lastSectionIndex && indexPath.row == lastRowIndex {
            tableView.contentOffset = CGPoint(x: 0, y: tableView.contentSize.height - tableView.bounds.size.height)
        }
    }
}

override func setEditing(_ editing: Bool, animated: Bool) {
    super.setEditing(editing, animated: animated)
    
    if editing {
        let tableView = superview as? UITableView
        let lastSectionIndex = tableView?.numberOfSections ?? 0 - 1
        let lastRowIndex = tableView?.numberOfRows(inSection: lastSectionIndex) ?? 0 - 1
        let lastIndexPath = IndexPath(row: lastRowIndex, section: lastSectionIndex)
        
        tableView?.scrollToRow(at: lastIndexPath, at: .bottom, animated: animated)
    }
}
