Idea for Accessibility of Tables

Often, I get ideas in my head and want to share them. Not long ago, I thought to myself: Is there a way to create access to tabular data, such as that from a spreadsheet, by combining tactile exploration with audio, either recorded by a voice talent or just using Voiceover on an iOS device?

I also wonder if it would be possible to create an app, or find an existing one, that would allow you to have a visual table on paper, if you want it, but have the data within the table read out, again, either with a voice talent or with Voiceover.

I realize that anyone who is using JAWS or Voiceover may have the ability to navigate tables, but I want to take it to the next level by combining the tactile ability to explore a table with a visual appearance that is both attractive and accessible.

I have two iOS devices, an iPhone and an iPad, both running iOS 10.2.

If anyone knows what apps are especially good for something like this, I'd like to hear about it. There may be an existing app that can do this, and I just don't know about it. If there isn't an app, maybe something can be developed by someone better at coding than I am.

Forgive the rambling nature of this post, but I wanted to get it out there and seek feedback. Thanks.
