Danny WhiteandJoshen Lim 66c48753e8 feat(studio): improve database column list scanning (#44208)
## What kind of change does this PR introduce?

UI improvements. Resolves DEPR-419.

## What is the current behavior?

- `ColumnList` splits type information across separate `Data Type` and
`Format` columns, which makes scanning less efficient
- The list only surfaces a limited subset of column metadata up front,
so key structural information like primary keys, foreign keys,
uniqueness, and identity is not easy to scan
- Constraint and nullability affordances are not aligned with the visual
language already used in the Table Editor and Schema Visualiser

## What is the new behavior?

- `ColumnList` now shows a leading type affordance icon, while keeping
the exact Postgres type visible in the `Type` column
- The standalone `Data Type` column is removed, and `format` is now the
primary textual type shown in the table
- The `Constraints` column now surfaces explicit icon-plus-label tokens
for:
  - `Primary`
  - `Foreign key`
  - `Unique`
  - `Identity`
  - `Nullable` / `Non-nullable`
- Constraint tokens use a purpose-built segmented style based on
`ComputeBadge`, including a green primary variant for primary keys
- Nullability now matches Schema Visualiser semantics exactly: outlined
diamond for nullable, filled diamond for non-nullable
- Existing search, descriptions, row actions, and permission gating are
preserved

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly
const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}

export default ComponentA
