# Sort Columns

Using the `order` option you can provide an order for the columns.

```javascript
import { Table } from 'voici.js'

const data = [
  { firstname: 'Homer', lastname: 'Simpson', age: 39 },
  { firstname: 'Marge', lastname: 'Simpson', age: 36 },
  { firstname: 'Bart', lastname: 'Simpson', age: 10 },
  { firstname: 'Lisa', lastname: 'Simpson', age: 8 },
  { firstname: 'Maggie', lastname: 'Simpson', age: 1 }
];

const config = {
  header: {
    order: ['age', 'lastname']
  }
};

const table = new Table(data, config);
table.printPlain();
```

Output:

```
  age    lastname    firstname  
================================
  39     Simpson     Homer      
  36     Simpson     Marge      
  10     Simpson     Bart       
  8      Simpson     Lisa       
  1      Simpson     Maggie     
```

{% hint style="info" %}
Columns not listed in `order` appear in their original order.
{% endhint %}
