@spec render(AshTui.State.t(), ExRatatui.Layout.Rect.t()) :: [
  {struct(), ExRatatui.Layout.Rect.t()}
]

Renders the relationships table for the current resource.

Returns a list of {widget, rect} tuples containing the relationships table (and optionally a scrollbar when content overflows). Relationships are navigable — pressing Enter on a row jumps to the destination resource.

Examples

iex> domains = AshTui.Introspection.from_data([
...>   %{
...>     name: MyApp.Accounts,
...>     resources: [
...>       %{
...>         name: MyApp.Accounts.User,
...>         attributes: [%{name: :id, type: :uuid, primary_key?: true}],
...>         actions: [],
...>         relationships: [%{name: :posts, type: :has_many, destination: MyApp.Blog.Post}]
...>       }
...>     ]
...>   }
...> ])
iex> state = AshTui.State.new(domains) |> Map.put(:current_tab, :relationships)
iex> rect = %ExRatatui.Layout.Rect{x: 0, y: 0, width: 60, height: 20}
iex> [{%ExRatatui.Widgets.Table{}, ^rect}] =
...>   AshTui.Views.RelationshipsTab.render(state, rect)
