Is it possible for ThingSpeak to show a simple table of all data collected?
Since ThingSpeak has an extensive API, you can build a tool to read in data and display it as a table. I have created a GitHub repo called, "IoT Debugger" that allows you to see data as a table as the it comes into a ThingSpeak Channel.

To use the demo, enter your channel number and the read API key.

If you want to modify the project, fork the project on GitHub.
