Swift 4 code: For tableview with no section headers you can add this code:

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

and you will get the header spacing to 0.

If you want a header of your specific height pass that value:

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

and the view from viewForHeaderinSection delegate.
