我正在使用邮件程序向包含优惠券的用户发送HTML丰富的电子邮件。每封电子邮件最多可包含10张优惠券，但我想为每张优惠券添加一个打印链接，允许他们只打印一张..我怎么能最好地完成这个...
mail.html.erb（没有样式）
<body>
<table width="100%" id="background" border="0" cellpadding="0" cellspacing="0">
<tr><td align="center" valign="top">
<table width="650" id="main" border="0" cellpadding="0" cellspacing="20">

<td id="header" colspan="2">
