टेबल व्यूसेल आकार को स्वचालित कैसे बनाएं?

मेरे पास एक टेबल व्यू सेल है और 4 बटन हैं लेकिन कुछ मामलों में मैं एक अयस्क और बटन छुपा रहा हूं और टेबल व्यू सेल का आकार स्वचालित कैसे बना सकता हूं ???

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "QuestionCell")!
     variant1 = cell.contentView.viewWithTag(1) as! UIButton
     variant2 = cell.contentView.viewWithTag(2) as! UIButton
     variant3 = cell.contentView.viewWithTag(3) as! UIButton
     variant4 = cell.contentView.viewWithTag(4) as! UIButton

    let questionTextView = cell.contentView.viewWithTag(5) as! UITextView
    questionTextView.text = "\(Questions[indexPath.row].content!), подсказка: \(Questions[indexPath.row].hint!)"
    variant1.addTarget(self, action: #selector(self.variant1ButtonPressed), for: .touchUpInside)
    variant2.addTarget(self, action: #selector(self.variant2ButtonPressed), for: .touchUpInside)
    variant3.addTarget(self, action: #selector(self.variant3ButtonPressed), for: .touchUpInside)
    variant4.addTarget(self, action: #selector(self.variant4ButtonPressed), for: .touchUpInside)
    //cell.contentView.backgroundColor = UIColor(red: 255/255, green: 0/255, blue: 0/255, alpha: 0.65)

    let numberOfVars = numberOfVariants[indexPath.row]
    if (numberOfVars == 2) {
        variant1.setTitle(Variants[0+amaunty[indexPath.row]].title, for: .normal)
        variant2.setTitle(Variants[1+amaunty[indexPath.row]].title, for: .normal)
        variant3.isHidden = true
        variant4.isHidden = true
    }
    else if (numberOfVars == 3){
        variant1.setTitle(Variants[0+amaunty[indexPath.row]].title, for: .normal)
        variant2.setTitle(Variants[1+amaunty[indexPath.row]].title, for: .normal)
        variant3.setTitle(Variants[2+amaunty[indexPath.row]].title, for: .normal)
        variant4.isHidden = true
    }
    else if (numberOfVars == 4) {
        variant1.setTitle(Variants[0+amaunty[indexPath.row]].title, for: .normal)
        variant2.setTitle(Variants[1+amaunty[indexPath.row]].title, for: .normal)
        variant3.setTitle(Variants[2+amaunty[indexPath.row]].title, for: .normal)
        variant4.setTitle(Variants[3+amaunty[indexPath.row]].title, for: .normal)
    }
    return cell
}
