大概67行左右，代码修改如下：
$css = '.rt-table{width:100%; max-width:640px; border-collapse:collapse; border:1px solid #e8e8e8; background:#fff;}.rt-label{width:120px; padding:10px 14px; background:#f7f7f7; border:1px solid #e8e8e8; text-align:center; color:#666; white-space:nowrap;}.rt-value{padding:10px 14px; border:1px solid #e8e8e8; text-align:left; color:#333;}';
$mail_body .= '<style>' . $css . '</style><table class="rt-table">';
foreach ($form as $value) {
$field_data = post($value->name);
if (is_array($field_data)) { // 如果是多选等情况时转换
$field_data = implode(',', $field_data);
}
$field_data = preg_replace_r('/pboot:if/i', '', $field_data);
if ($value->required && ! $field_data) {
alert_back($value->description . '不能为空！');
} else {
$data[$value->name] = $field_data;
$mail_body .= '<tr>';
$mail_body .= '<td class="rt-label">';
$mail_body .= $value->description . '</td>';
$mail_body .= '<td class="rt-value">';
$mail_body .= $field_data . '</td></tr>';
}
}
$mail_body .= '</table>';
