Spacing between row in newsletter html table in Hotmail and Gmail

Question

I try to create an newsletter.

The display is perfect on web browser, perfect in thunderbird too... but in webmails like Gmail or Hotmail... I have spaces between the rows.

Here is my code :

<center><a href="http://www.itbag.fr/newsletter/03022012/" style="color:#E84691;font-size:10px;">Si la newsletter s'affiche mal, consultez la en ligne</a>
<table id="Table_01" width="731" height="731" border="0" cellpadding="0" cellspacing="0">
<tr>
    <td colspan="3" align="left" valign="top">
        <a href="http://www.itbag.fr" style="display:block;height:131px">
