浏览器无法解释html模板

I have one function in a very small Go application that does a query to a database, retrieves some data and inserts it in the template (main.html). the data is getting inserted into the template (see image), however the html is not being interpreted by the browser (Chrome and Firefox) enter image description here . My browsers are otherwise working fine. Is there something that I'm not doing correct with the template?

func Root(w http.ResponseWriter, r *http.Request) {

    t := template.Must(template.New("main").ParseFiles("main.html"))
    rows, err := db.Query("SELECT title, author, description FROM books")
    PanicIf(err)
    defer rows.Close()

    books := []Book{}

    for rows.Next() {
        b := Book{}
        err := rows.Scan(&b.Title, &b.Author, &b.Description)
        PanicIf(err)
        books = append(books, b)
    }
    t.ExecuteTemplate(w, "main.html", books)

}

main.html

<html>
  <head>
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.0/css/bootstrap.min.css">
  </head>


  <body>

    <div class="container">
     <table class="table">
  <tr>
    <th>Title</th>
    <th>Author</th>
    <th>Description</th>
  </tr>
{{ range . }}
  <tr>
    <td>{{.Title}}</td>
    <td>{{.Author}}</td>
    <td>{{.Description}}</td>
  </tr>
{{ end }}
</table>
    </div>
  </body>


</html>

You need to set the content type, although it's rather weird it didn't automatically set it for you.

w.Header().Set("Content-Type", "text/html; charset=utf-8")
t.ExecuteTemplate(w, "main.html", books)

//edit

Also for correctness sake, you should add <!DOCTYPE html> to the top of your template, not related to the problem though.

Most likely you are doing import "text/template" and should be doing import "html/template", but the other answer will also fix it for you.
