I'm wondering what the best way to present a table for mobile view in terms of SEO? It's a complicated table (not simple rows & columns but also col spans) which doesn't work with any responsive techniques I can find. I can offer different content for desktop / mobile so desktop is OK. But what's the best way forward with Google for mobile? I could offer a jpg or simply an explanation to revisit the page on desktop, but neither of those options  seem particularly Google-friendly?
