TableView Sections not moving

Hello!
Thank you for your library!
I note that Table view sections do not moving when scrolling enabled.
```
import UIKit
import AMScrollingNavbar

class TVCTableViewController: UITableViewController {

override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)

if let navigationController = navigationController as? ScrollingNavigationController {
print("FOLLOW")
navigationController.followScrollView(tableView, delay: 0)
}
}

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 60))
view.backgroundColor = .red
return view
}

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 60.0
}

// MARK: - Table view data source

override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 20
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)

return cell
}

}
```
