Swift 3 version of Young Hoo Kim's answer works for me:

func generateTableViewImage(_ tableView: UITableView) -> UIImage? {
    UIGraphicsBeginImageContextWithOptions(tableView.contentSize, false, UIScreen.main.scale)

    for section in 0..<tableView.numberOfSections {
        for row in 0..<tableView.numberOfRows(inSection: section) {
            let indexPath = IndexPath(row: row, section: section)
            guard let cell = tableView.cellForRow(at: indexPath) else { continue }
            cell.contentView.drawHierarchy(in: cell.frame, afterScreenUpdates: true)
        }
    }
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image
}

It should be noted that if your UITableView is particularly long you may not be able to capture it with the function above as it may require too large an image.
