How to update tableView cell's labels when every time i enter new value in textField?

How to update tableView cell's labels when every time i enter new value in textField?

@objc func doneClicked() {
        view.endEditing(true)

        //MARK: - ФОРМАТТЕР
        let formatter = NumberFormatter()
        formatter.locale = Locale.current
        formatter.numberStyle = .decimal
        formatter.minimumFractionDigits = 3
        formatter.maximumFractionDigits = 6

         if let text = textField.text, let number = formatter.number(from: text) {

            atmosfera = number.doubleValue

            print(atmosfera)


        }
    }

This func is button for toolbar in keyboard. When i press "Done" my keyboard close and value is updated.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


            let cell1 = tableView.dequeueReusableCell(withIdentifier: "resultCell") as! resultTableViewCell


            cell1.nameResult.text = converters[indexPath.row]
            cell1.labelResult.text = String(convertatmo[indexPath.row] * atmosfera)


            return cell1


    }

This is my cells.

Every time when I press Done button on keyboard I save a new value to atmosfera var. I want to update my labelResult.labels. How I could do it?

Add tableView.reloadData() after you update the atmosfera var, that will reload the tableView with the new data.

Call reloadData instance method of the tableView any time you want to refresh the whole table

 if let text = textField.text, let number = formatter.number(from: text) {

        atmosfera = number.doubleValue

        print(atmosfera)

        self.tableView.reloadData()

    }

 func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
}
