I think everyone forgets that UITableView is a UIScrollView after all. There is no need to calculate cells, height etc. You can simply create your context with the contentSize, set tableView.frame.size = tableView.contentSize and render in context.

Please see this example

        UIGraphicsBeginImageContext(tableView.contentSize)
        let context = UIGraphicsGetCurrentContext()

        let cachedOffset = CGPoint(x:tableView.contentOffset.x , y:tableView.contentOffset.y)
        let cachedFrame = tableView.frame

        tableView.contentOffset = .zero
        tableView.frame = CGRect(x: 0, y: 0, width: tableView.contentSize.width, height: tableView.contentSize.height)
        tableView.layer.render(in: context)

        tableView.frame = cachedFrame
        tableView.contentOffset = cachedOffset

        if let image = UIGraphicsGetImageFromCurrentImageContext() {
            let imageView = UIImageView(image: image)
            self.createPDF(fromUIViews:myImage saveToDocumentsWithFileName:"PDF Name")
        }

        UIGraphicsEndImageContext()
