What @Robert Sterbal-482516 is trying to say is that a wiki can allows you to sort the column from A to Z.
The goal is to filter by Platform or by Cost. The GitHub table doesn't allows you to do so.
There are a few alternatives:
1) You can simply drag and drop your spreadsheet: https://help.github.com/articles/file-attachments-on-issues-and-pull-requests/
2) You can upload the spreadsheet to Google Sheet and then copy/paste the embedded code to GitHub
🙂 Basically we need raw data 🙂
Thank you so much for your work
