Can't show tableview in my ViewController

I need a simple UITableView of 1 row and 6 columns, I'm trying to create a UITableView programmatically and add it on my ViewController but with no luck, I watched some tutorials and I don't really get what I'm doing wrong. Maybe if you guys take a look you could tell me. This is my code:

class MainVC: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var mTableView: UITableView = {

        //STACKOVERFLOW *In the first line, I'm just positioning it randomly to see if I can get the table view to show, will change later.*
        var tableView = UITableView(frame: CGRect(x: 100, y: 100, width: 100, height: 100), style: .plain)
        tableView.backgroundColor = .red

        tableView.translatesAutoresizingMaskIntoConstraints = false
        return tableView

    }()

    override func viewDidLoad() {

        super.viewDidLoad()
        view.backgroundColor = UIColor(red: 80/255, green: 135/255, blue: 179/255, alpha: 1.0)

        setupNavBar()
        self.navigationItem.searchController = mSearchBarController

        setupMainWeatherIcon()
        setupTableView()

        mTableView.dataSource = self
        mTableView.delegate = self

    }

    private func setupTableView(){

        self.view.addSubview(mTableView)


        mTableView.leadingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.leadingAnchor).isActive = true
        mTableView.trailingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.trailingAnchor).isActive = true
        mTableView.centerXAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.centerXAnchor).isActive = true
        mTableView.centerYAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.centerYAnchor).isActive = true

    }

    // MARK: TABLE VIEW METHODS!
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        return tableView.dequeueReusableCell(withIdentifier: "forecastCell", for: indexPath)
    }
}

You forgot to setup datasource for tableView

Add: mTableView.dataSource = self

UITableViewController add this automatically, UIViewController doesn't.

Also you forgot to setup height anchor... and Width. Or Top and Bottom Anchor
