HTML签名在行与行之间留有较大的空格（Outlook的Gmail应用）。

Question

这是GMail手机应用中从Outlook发送时的样子。

如何避免这些大的空白？

我的代码如下。

<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;">

    </tr>
