Some TableFormat tables for Roll20.
I assume there are other methods here, but this is what I use.
- Download the Roll20 VTT Enhancement Suite for your browser
- Open up your game and go to the Collection tab
- Scroll down to the Import Rollable Table section
- Click "Import TableExport (Paste text)"
- Copy the contents of the table you want to import and paste it into the form
- Hit submit
- Follow the instructions on how to use rollable tables in the Roll20 wiki
