[GitHub] [airflow] turbaszek opened a new pull request #11061: Add template fields renderers for better UI rendering

[GitBox]

turbaszek opened a new pull request #11061:
URL: https://github.com/apache/airflow/pull/11061


   This PR adds possibility to define template_fields_renderers for an
   operator. In this way, users will be able to provide information
   on what lexer should be used for rendering a particular field. This is
   super useful for custom operator and gives more flexibility than
   predefined keywords.
