What happened?

While investigating the issue #24675, a separate streaming-related rendering bug was discovered. During streaming, tables are re-rendered on every chunk instead of waiting for the complete table output.

<img width="617" height="704" alt="Image" src="https://github.com/user-attachments/assets/b53aba5e-d06a-4d2c-8778-51569926707a" />

This causes:

  • The top border ┌──┬──┐ to appear on the same line as [Model:]
  • The table growing row by row visually as chunks arrive
  • Multiple partial re-renders of the same table before it completes

What did you expect to happen?

The table should be held in a buffer until the full table is received (i.e. a non-table line or EOF is encountered), then rendered once completely.

TL;DR

Buffering the table output until a complete table is received may resolve the streaming-related rendering bug.

Guidance

  • Investigate the current rendering logic to identify why tables are being re-rendered on every chunk instead of waiting for the complete table output.
  • Consider implementing a buffering mechanism to hold the table output until a non-table line or EOF is encountered.
  • Review the streaming protocol to ensure it provides a clear indication of when a table is complete.
  • Verify that the rendering issue is specific to streaming and does not occur with non-streaming table output.

Example

No code snippet can be provided without more information about the current implementation.

Notes

The solution may depend on the specific requirements of the streaming protocol and the rendering logic. Additional information about the protocol and the current implementation may be necessary to provide a more detailed solution.

Recommendation

Apply workaround: Implement a buffering mechanism to hold the table output until a complete table is received, as this approach directly addresses the reported issue and can be implemented without requiring additional information about the protocol or rendering logic.
