How do I add multiple links in each table row form table?
After a long research i was able to acheive this as follows:


$approve_link = Link::fromTextAndUrl(t('Approve'), Url::fromRoute('vacation_forms.operations', ['ID' => $result->id, 'action' => 'approve']))->toString();
$reject_link = Link::fromTextAndUrl(t('Reject'), Url::fromRoute('vacation_forms.operations', ['ID' => $result->id, 'action' => 'reject']))->toString();
$mainLink = t('@linkApprove&nbsp;|&nbsp;@linkReject', array('@linkApprove' => $approve_link, '@linkReject' => $reject_link));


and then use $mainLink in foreach loop.
Thanks for all your help.
