# NSTableView Printing Test
This is a demo project so you can check out how printing a table could work.
The goal here is to show tabular data on screen, and add text for print-outs.
Print dialog
PDF result
## Discussion
`NSView`-based printing is a bit odd since it prints whatever `NSView.draw(_:)` produces. We can customzie that by overriding the `draw` method. But for a table view? Embedding a stock standard table view in a custom view hierarchy sounds more promising.
To add a multi-line label on page, we cannot use the stock view-based printing options since the label is not part of the view hierarchy. We need to set up our own view hierarchy with all the to-be-printed views.
For the simple page layout used here, I picked a vertical `NSStackView`. This can be printed via `NSPrintOperation(view: stackView)` and then showing the print dialog for that.
For complex floating layouts, a `NSTextView` with an attributed string and maybe even a custom `NSLayoutManager` might be necessary. That's how you could, in theory, get text wrapped around images or small tables like Pages does it.
Actually recommended by other devs: use `WKWebView` and HTML. WebKit does a great job with complex layouts; just look at Safari. Then you can export the web view's content as PDF, and then use the PDF data for the print dialog directly.
