Codesandbox Case

Behavior
The documentation seems to imply that a TreeTable has a responsive mode which can be enabled by setting the "responsive" prop to true. However, no such prop appears to exist.

Looking at the Treetable.d.ts on git seems to imply that such a prop has never existed.

This occurs in 3.4.0 and 4.2.0.

Please see;

#1250

We've decided not to make it built-in as it restricts the flexibility, instead we'll provide demos.

Until it is deprecated in 4.2.0, I'll fix this issue for 4.1.1

Just realized that, it is due to a doc error, there is no need for a responsive prop in TreeTable. Please apply the demo solution in comment above.
