## Example

In this example, we will load the data from the Local Table and display it in a flatlist component.

```js
Note: This example will only work after the user has created the data using `Dataset.insert` function.
```

### Steps

1. Make sure a `Local Table` component is created and filled on the services panel in the service page.

   ![](/files/JzmCMH8Z7655Mt4p1eaz)
2. Drag a button component to a page in the mobile designer.

   ![](/files/O8ag5WhlbzpaiYiA7ijX)
3. Drag a `flatlist` component to a page in the mobile designer, and drag a `label` component into the `flatlist` component.

   ![](/files/Tcey4eR6R8Dq9TGX2e4o)
4. Fill the `flatlist` component property in the page and fill the `label` component property in the `flatlist` component, make sure the `label` component `field` value matches the key of the data that is being stored in the local table.

   ![](/files/K4py5Dfa6ig9cnKm1rB2)
5. Select the event `press` and drag the `Dataset.loadData` function to the event flow. Fill in the parameters of the function.
