如何对Flask分页对象中的项进行编号？

from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
from flask_paginate import Pagination, get_page_args

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'your_database_uri'
db = SQLAlchemy(app)

class Item(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(100))

@app.route('/')
def index():
    page, per_page, offset = get_page_args()
    items = Item.query.paginate(page, per_page, error_out=False)
    pagination = Pagination(page=page, per_page=per_page, total=items.total)
    return render_template('index.html', items=items, pagination=pagination)

@app.template_filter('enumerate')
def paginate_enumerate(seq, start=1):
    return enumerate(seq, start=start)

if __name__ == '__main__':
    app.run()
