### Proposal

I would like the HTML in a td to be returned. This could be done by passing an option to parseFile:

```php
$sites = Parser::new()
->ignoreTableHeader()
->tableHeader(['dir', 'port', 'domains'])
->parseFile('http://127.0.0.1:7080');
```

The content is


But what's being returned is a single string:

^ "https://*.pgsc.wip/https://pgsc.wip/"

If I had the HTML I could parse it to get the 2 elements I need.

Thanks for your consideration.
