# Selected Columns

Select certain columns from your dataset you want to show.

Using the `include` option you can provide an array of columns to show.

```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: {
    include: ['firstname', 'lastname']
  }
};

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

Output:

```
  firstname    lastname  
=========================
  Homer        Simpson   
  Marge        Simpson   
  Bart         Simpson   
  Lisa         Simpson   
  Maggie       Simpson   
```
