Since you support GFM style tables, I'd expect this aspect of GFM supported as well.

Research direction
Investigate the Markdown rendering pipeline in the Mattermost web app. Look for the markdown parser library (e.g., react markdown, marked) and check if it supports nested tables inside list items. The issue likely resides in the frontend code under webapp/components/markdown. Since the issue is assigned, coordinate with the assignee to avoid duplicate work.
