self.myTableView.translatesAutoresizingMaskIntoConstraints = false

self.view.addConstraint(NSLayoutConstraint(item: self.myTableView, attribute: .top, relatedBy: .equal, toItem: self.view, attribute: .top, multiplier: 1.0, constant: 0))

self.view.addConstraint(NSLayoutConstraint(item: self.myTableView, attribute: .bottom, relatedBy: .equal, toItem: self.view, attribute: .bottom, multiplier: 1.0, constant: 0))

self.view.addConstraint(NSLayoutConstraint(item: self.myTableView, attribute: .leading, relatedBy: .equal, toItem: self.view, attribute: .leading, multiplier: 1.0, constant: 0))
