HTML signature leaves big spaces between rows (Gmail App from Outlook) - outlook

Question

This is how it looks in GMail mobile app when sent from Outlook:
How can I avoid those big gaps?
My code is as follows:
<table id="sig" width='320' cellspacing='0' cellpadding='0' border-spacing='0' style="width:320px;margin:0;padding:0;">
<tr>
<td valign='top' width="120" height="48" style="width:120px;height:48px;margin:0;padding:0;vertical-align:top;">
<a style="border:none;text-decoration:none;">
<img moz-do-not-send="true" src="https://s3.amazonaws.com/media_crisalix/signatures/logo.jpg" alt="Crisalix" width='120' height='48' style="border:none;width:120px;height:48px;display:block;">
</a>
</td>
</tr>
