1. Is this request related to a challenge you're experiencing? Tell me about your story.

Currently, the results returned by batch operations in the workflow have all fields placed in a single column, which can cause inconvenience in viewing and parsing the results. Would it be possible to expand them into different columns? If feasible, I can submit a PR to improve this experience.

2. Additional context or comments

Current behavior: all output fields placed in a single column with json format

Expected behavior: each output fields placed in different column like input fields
