 `{% block main %}
    <table class="table">
        <thead class="thead-dark">
           <tr>
               <th scope="col">Food</th>
               <th scope="col">Food Freshness</th>
               <th scope="col">Feed this number of people</th>

          </tr>
       </thead>
       <tbody>
     {% for r in req %}
           <tr>
             <th scope="row">{{ r[0] }}</th>
             <td>{{ r[1] }}</td>
         <td>{{ r[2] }}</td>
         <td>{{ r[3] }}</td>  
         <td>{{ r[4] }}</td>  
        </tr>
  {% endfor %}
    </tbody>
</table>

{%endblock%}`

这是我的python代码:https://pastebin.com/ehsaawi8

@app.route("/index1")
@login_required
def index1():
    rows = db.execute("SELECT * FROM req WHERE user_id = :user",user=session["user_id"])
    req = []
    for row in rows:
       req.append(list((row['food'], row['foodf'], row['nosofp'], row['timep'], row['address'])))

    return render_template("index1.html", req=req)

问题是身体，头部很好。
