Hi Tobias,
I am using your Tablepress and so far so good. Even I was wondering of how to integrate a CSV file with my Widget.
An example - http://www.newtechnology.co.in/iphone-5-price-in-india/
It's a product review affiliate site and I want to add such a feature on my site too. As you can see there's a price comparison on the right side and it is updated on its own with the product feed. I was able to create a table with those values but then I realized that the Table will be the same for ALL the posts.
Can we somehow integrate Tablepress (in the sidebar text widget) with the post_IDs AND integrate it with the data feed too?
I really like your plugin and would love to donate to get that feature too.
Regards,
malania
