[R] datatable using dt not able to print background colors

[Valentin Petzel]

Hello Matt,

I do not think that this is the best place for troubleshooting Chrome issues. If your html file shows the colors but print doesn't then the page probably uses different stylesheets for display and print. You might want to inspect the html for something like this. If you need help, the answers to this should get you there:
