I have used other markdown editors that seem to work fine interpreting indented tables, at least if within a list context (Github, VSCode). Using within a list would be my primary use case anyway, so maybe I should have used that as my example.
For reference, this gets interpreted as an indented table within VSCode:
1. Item 1
2. Item 2 with table
| Table | Test |
| --- | --- |
| A | B |
3. Item 3
