Tables and Inline CSS causing problems in Hotmail and Gmail

Question

I am making an email signature using only text rather than an image attachment. I have recreated the logo using HTML and inline CSS. I cannot get it to display correctly in Gmail or Hotmail. It is pushing the 5 blue squares out of alignment. Does anyone have any ideas why this might be? Here is the code and I have added colour backgrounds behind the offending parts to try and figure it out.

<style type="text/css">
a.link{margin:0;padding:0;border:none;text-decoration:none;}
</style>
