1. Review Summary: This diff removes the tablewriter library and replaces it with a simpler, custom table printing function. While it reduces dependencies, the custom implementation is very basic and lacks features of the removed library.

2. Critical issues: None

3. Suggestions:

   • Reconsider table implementation: The current printTable function provides a very basic table output. While reducing dependencies is good, the functionality is severely limited. Consider alternatives like using text/template for better formatting or exploring lightweight table formatting libraries if more control is needed.
   • Move printTable to internal package: Since printTable is only used inside output package it is good to move this function to internal package. That will improve package boundary.
   • Error handling: The Response function returns only one error at the end of the function, it's better to return as soon as possible and clarify the context
   • Test table output: Add tests to verify the table output format. This will help prevent regressions when the table formatting logic is modified.
   • Consider separating concerns: The Response function now directly handles printing the table. It could be more SOLID to have the output logic in a separate function or type that Response calls. This improves testability and maintainability.

4. Quick wins: Successfully removed a large dependency. Code is simpler.
