How to use tableView propriety in a UITableViewCell class

In my swift project I have a tableViewController, with class TableViewController, and one prototype cell, with class TableViewCell. Now I want to use: tableView.reloadData(), or other function, in the class TableViewCell. I put a button into the prototype cell, here the code: 

class TableViewCell: UITableViewCell {

   let tableViewController = TableViewController()

    @IBAction func actionButton(_ sender: UIButton) {

    tableViewController.tableView.reloadData() // or other function 

}
}

by this method the result is: unexpectedly found nil while unwrapping an optional value. I checked that the class TableViewController is loaded before than the class TableViewCell, so I don't found the problem. Can you help me to find how this error occur?
