Android : Send a table structure in mail (android code)

I'm trying to send a mail intend in android, which contains a table structure, with some test results.

For the generated text part (the main part of the mail), i tried to use a code like this:

         Html.fromHtml(
           new StringBuilder()

        .append("<table style=\"width:100%\"><tr>\n" +
            "    <td>Jill</td>\n" +
            "    <td>Smith</td> \n" +
            "    <td>50</td>\n" +
            "  </tr>\n")
       .append(
            "  <tr>\n" +
            "    <td>Eve</td>\n" +
            "    <td>Jackson</td> \n" +
            "    <td>94</td>\n" +
            "  </tr></table>")
        .append("<small><p>More content</p></small>")
        .toString());

It sends the mail, but all the information is like this: Jill Smith50.....

What shoud I change? Do you have any other idea? Thank you!
