模板格式处理如下，注意这个神奇的“-”符号，它的位置可以写在花括号内部的前后：
<!DOCTYPE html>
<html>
<head>
<title>模板中如何插入数据？</title>
<Meta http-equiv="Content-Type" content="text/html" charset="utf-8">
<Meta name="keywords" content="关键词1,关键词2">
<Meta name="description" content="">
<style>
span {display:block;width:100px;float:left;}
</style>
</head>
<body>
<div>
<h3>输出嵌套字段内容</h3>
<p><b>{{.UserName}}</b><p>
<ul>
{{range .Emails -}}
<li>{{.}}</li>
{{- end}}
</ul>
<ul>
{{with .Friends -}}
{{range . -}}
<li><span>{{.Fname}}</span><span>{{.Age}}</span><span>{{.Mobile}}</span></li>
{{- end}}
{{- end}}
</ul>
</div>
</body>
</html>
神奇的减号“-”，去掉Go Template生成的标签换行符：
<html>
<head>
<title>模板中如何插入数据？</title>
<Meta http-equiv="Content-Type" content="text/html" charset="utf-8">
<Meta name="keywords" content="关键词1,关键词2">
<Meta name="description" content="">
<style>
span {display:block;width:100px;float:left;}
</style>
</head>
<body>
<div>
<h3>输出嵌套字段内容</h3>
<p><b>{{.UserName}}</b><p>
<ul>
{{- range .Emails}}
<li>{{.}}</li>
{{- end}}
</ul>
<ul>
{{- with .Friends}}
{{- range .}}
<li><span>{{.Fname}}</span><span>{{.Age}}</span><span>{{.Mobile}}</span></li>
{{- end}}
{{- end}}
</ul>
</div>
</body>
</html>
