如何在golang模板中使用数组对象？

type Person struct {
    Name string
    Age  int
}

type PageData struct {
    People []Person
}

data := PageData{
    People: []Person{
        {Name: "Alice", Age: 25},
        {Name: "Bob", Age: 30},
        {Name: "Charlie", Age: 35},
    },
}

tmpl, err := template.New("example").Parse(`
    <h1>People:</h1>
    <ul>
        {{range .People}}
            <li>{{.Name}} ({{.Age}} years old)</li>
        {{end}}
    </ul>
`)

if err != nil {
    // 错误处理
}

err = tmpl.Execute(os.Stdout, data)
if err != nil {
    // 错误处理
}
