How to get table row of a website that updates dynamically (simple html DOM parser)?

Question

Basically what I want to do is get a particular table row of a website. the table has an id of "table-data". I have already written the PHP but I noticed that the file_get_html doesn't actually get the data that is dynamically loaded. How should I approach?

include_once('simple_html_dom.php');

$html = file_get_html('http://www.2gheroon.ir');
$es = $html->find('table.data-table');

for ($i=0 ; $i<count($es); $i++) {
    echo $es[$i]->plaintext;
}

echo $html;
