### \_reactivity

```ts
readonly _reactivity: TableReactivityBindings;
```

Defined in: [core/table/coreTablesFeature.types.ts:162](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L162)

Table reactivity bindings for interacting with TanStack Store.

***

### \_rowModelFns

```ts
readonly _rowModelFns: RowModelFns<TFeatures, TData>;
```

Defined in: [core/table/coreTablesFeature.types.ts:182](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L182)

The row model processing functions that are used to process the data by features.

***

### \_rowModels

```ts
readonly _rowModels: CachedRowModels<TFeatures, TData>;
```

Defined in: [core/table/coreTablesFeature.types.ts:186](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L186)

The row models that are enabled for the table.

***

### \_rowPrototype?

```ts
optional _rowPrototype: object;
```

Defined in: [core/table/coreTablesFeature.types.ts:190](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L190)

Prototype cache for Row objects - shared by all rows in this table

***

### atoms

```ts
readonly atoms: Atoms<TFeatures>;
```

Defined in: [core/table/coreTablesFeature.types.ts:196](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L196)

The readonly derived atoms for each `TableState` slice. Each derives from
its corresponding `baseAtom` plus, optionally, a per-slice external atom or
external state value (precedence: external atom > external state > base atom).

***

### baseAtoms

```ts
readonly baseAtoms: BaseAtoms<TFeatures>;
```

Defined in: [core/table/coreTablesFeature.types.ts:201](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L201)

The internal writable atoms for each `TableState` slice. This is the library's
single write surface — all state mutations from features land here.

***

### initialState

```ts
readonly initialState: ExtractFeatureMapTypes<TFeatures>;
```

Defined in: [core/table/coreTablesFeature.types.ts:205](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L205)

This is the resolved initial state of the table.

***

### options

```ts
readonly options: TableOptions<TFeatures, TData>;
```

Defined in: [core/table/coreTablesFeature.types.ts:209](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L209)

A read-only reference to the table's current options.

***

### optionsStore?

```ts
readonly optional optionsStore: Atom<TableOptions<TFeatures, TData>>;
```

Defined in: [core/table/coreTablesFeature.types.ts:215](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L215)

Writable atom for table options. Only created when `createOptionsStore` is
true on the active core reactivity bindings. Adapters that opt out keep
options as plain resolved data instead of backing them with an atom.

***

### store

```ts
readonly store: ReadonlyStore<ExtractFeatureMapTypes<TFeatures, TableState_FeatureMap>>;
```

Defined in: [core/table/coreTablesFeature.types.ts:220](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/table/coreTablesFeature.types.ts#L220)

The readonly flat store for the table state. Derives from `table.atoms`
only; never reads external state directly.
