curr.execute("select cate, valu from tb order by cate, valu")
result = [
(cate, [v[1] for v in valus])
for cate, valus in groupby(curr, lambda row: row[0])
]
return render_template('page.html', data = result)
page.html:
{% for cate, vals in data %}
<tr><td>{{ cate }}</td><td></td></tr>
{% for val in vals %}
<tr><td></td><td>{{ val }}</td></tr>
{% endfor %}
{% endfor %}
