  Register Angular Table v9 instances with injectTanStackTableDevtools inside injection context. Load for reactive table registration, required options.key, enabled or undefined tables, cleanup, Angular isDevMode gating, or explicit production exports.

This skill builds on @tanstack/table-core#core and @tanstack/table-devtools#devtools.

## Setup

```ts
import { Component } from '@angular/core'
import { injectTable, tableFeatures } from '@tanstack/angular-table'
import { injectTanStackTableDevtools } from '@tanstack/angular-table-devtools'

const features = tableFeatures({})
const columns = [{ accessorKey: 'id' }]
const data: Array<{ id: string }> = []

@Component({ selector: 'users-table', template: 'Users table registered' })
export class UsersTable {
  readonly table = injectTable(() => ({
    key: 'users-table',
    features,
    columns,
    data,
  }))

  constructor() {
    injectTanStackTableDevtools(() => ({ table: this.table }))
  }
}
```

Provide the Angular TanStack Devtools host once at application configuration level as documented in `docs/devtools.md`.

## Hooks and Components

The injector options function may return `table: undefined` or an `enabled` function to remove/disable registration reactively.

## Common Mistakes

### CRITICAL Injector called outside context

Wrong: call `injectTanStackTableDevtools` from an arbitrary callback after bootstrap.

Correct: call it in a component/service field initializer or constructor injection context.

The adapter uses Angular injection and effects for lifecycle cleanup.

Source: TanStack/table:packages/angular-table-devtools/src/injectTanStackTableDevtools.ts

### HIGH Missing table key

Wrong: register an otherwise valid table without `options.key`.

Correct: assign a stable unique key before injection registration.

Core registration logs an error and skips keyless targets.

Source: TanStack/table:packages/table-devtools/src/tableTarget.ts

### MEDIUM isDevMode no-op misunderstood

Wrong: expect default Angular exports to render production Devtools.

Correct: keep standard setup development-only; use `/production` only when explicitly requested.

The package index switches exports using Angular `isDevMode()`.

## API Discovery

Inspect `node_modules/@tanstack/angular-table-devtools/dist/index.d.ts` and `injectTanStackTableDevtools.d.ts` for current injection options.
