Story

As a platform engineer using RHDH, I want to add custom columns to the Catalog table that display values from entity metadata, annotations, or spec fields so that I can surface organization-specific information without developing custom plugins.

Background

Organizations often add custom annotations to entities (e.g., custom/security-tier, custom/cost-center, custom/team-lead). Currently, this metadata is only visible when viewing individual entity details. Displaying this information in the catalog table would improve discoverability.

Acceptance Criteria

[ ] Platform engineer can add the custom columns by adding below config in app-config.yaml

app:
  catalog:
    table:
      columns:
        custom:
          - title: Security Tier
            field: "metadata.annotations['custom/security-tier']"
            width: 120
            defaultValue: Unclassified
          - title: Cost Center
            field: "metadata.annotations['finance/cost-center']"
            sortable: true
          - title: Team
            field: spec.team

[ ] Platform engineer can add catalog.table.columns.custom array in app-config.yaml
[ ] Each custom column supports:

• [ ] title (required) - Column header text
• [ ] field (required) - Entity field path
• [ ] width (optional) - Column width in pixels
• [ ] sortable (optional, default: true) - Enable/disable sorting
• [ ] defaultValue (optional) - Value when field is missing
  [ ] Field paths support dot notation: spec.team, metadata.namespace
  [ ] Field paths support bracket notation for annotations: metadata.annotations['custom/security-tier']
  [ ] Custom columns are appended after built-in columns
  [ ] Custom columns support sorting when sortable: true
  upstream documentation updates (design docs, release notes etc)
