Unable to get HTML formatting to work in GMAIL

Question

I have a powershell script that sends out an HTML formatted email, the formatting looks perfect in Outlook but does not work in GMAIL, any suggestions? The HTML used is:

#HTML 
$a = "<style>"
$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"
$a = $a + "TH{border-width: 1px;padding: 10px;border-style: solid;border-color: black;}"
$a = $a + "TD{border-width: 1px;padding: 10px;border-style: solid;border-color: black;}"
$a = $a + "</style>"

Thanks.

Solution

GMail tends to prefer inline styles. As such:

<table style="border: 1px solid black; border-style: collapse;">
     <tr style="border: 1px solid black; padding: 10px;">
          <td style="border: 1px solid black; padding: 10px;">
          </td>
     </tr>
</table>

don't you mean border-collapse: collapse?
