For Swift:

  1. Create outlet for UIPickerView in custom table view class:

    class MyTableViewCell: UITableViewCell, UIPickerViewDelegate, UIPickerViewDataSource {
    @IBOutlet var myPickerView: UIPickerView!
}

  2. Add delegate and datasource in "cellForRowAtIndexPath" in ViewController:

    class myViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource, UITableViewDelegate, UITableViewDataSource {
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {            
        let cell = tableView.dequeueReusableCellWithIdentifier("myCell") as! MyTableViewCell

        cell.myPickerView.dataSource = self
        cell.myPickerView.delegate = self

        return cell
    }
}

You could have your tableView controller set a property on the tableview cells as they are created indicating that it is the delegate and datasource.

On the tableviewcell class you created just add a property that is an instance of you tableview controller. Like

@property (nonatomic, retain) MyTableViewController * pickerDelegate;

Then in your cellForRowAtIndexPath you can set that property to self

cell.pickerDelegate = self;

You might need to also set some sort extra property like a tag to distinguish between each cell. I would think another property on the tableviewcell like an NSIndexPath would do.
