Dynamic table display using kivy and sqlite 3

Question

I am working on a GUI to manage inventory (Python 3.4, Sqlite3 and Kivy 1.9.1) and the idea is to be able to recognize products based on their different features, w

Yes, you can use RecycleView for this.
Try this example:

import sqlite3 as lite

con = lite.connect('test.db')
cur = con.cursor()

try:
    with con:
        cur.execute("CREATE TABLE Cars(Id INT, Name TEXT, Price INT)")
        cur.execute("INSERT INTO Cars VALUES(1,'Audi',52642)")
        cur.execute("INSERT INTO Cars VALUES(2,'Mercedes',57127)")
        cur.execute("INSERT INTO Cars VALUES(3,'Skoda',9000)")
        cur.execute("INSERT INTO Cars VALUES(4,'Volvo',29000)")
        cur.execute("INSERT INTO Cars VALUES(5,'Bentley',350000)")
        cur.execute("INSERT INTO Cars VALUES(6,'Citroen',21000)")
        cur.execute("INSERT INTO Cars VALUES(7,'Hummer',41400)")
        cur.execute("INSERT INTO Cars VALUES(8,'Volkswagen',21600)")
except:
    pass


from kivy.uix.boxlayout import BoxLayout
from kivy.base import runTouchApp
from kivy.lang import Builder
from kivy.properties import ListProperty


Builder.load_string("""

<MyLayout>:
    Button:
        text: "Get data"
        on_press: root.get_data()
    RecycleView:
        data: [{'text':"Id:{} Brand:{} Km:{}".format(id,name,km)} for id,name,km in root.rows]
        viewclass: "Label"
        RecycleBoxLayout:
            default_size: None, dp(56)
            default_size_hint: 1, None
            size_hint_y: None
            height: self.minimum_height
            orientation: 'vertical'

""")


class MyLayout(BoxLayout):
    rows = ListProperty([("Id","Brand","Price")])
    def get_data(self):
        cur.execute("SELECT * FROM Cars")
        self.rows = cur.fetchall()
        print(self.rows)


runTouchApp(MyLayout())

Slightly modifying the original solution from @el3ien for better look and feel :-

import sqlite3 as lite

con = lite.connect('test.db')
cur = con.cursor()

try:
    with con:
        cur.execute("CREATE TABLE Cars(Id INT, Name TEXT, Price INT)")
        cur.execute("INSERT INTO Cars VALUES(1,'Audi',52642)")
        cur.execute("INSERT INTO Cars VALUES(2,'Mercedes',57127)")
        cur.execute("INSERT INTO Cars VALUES(3,'Skoda',9000)")
        cur.execute("INSERT INTO Cars VALUES(4,'Volvo',29000)")
        cur.execute("INSERT INTO Cars VALUES(5,'Bentley',350000)")
        cur.execute("INSERT INTO Cars VALUES(6,'Citroen',21000)")
        cur.execute("INSERT INTO Cars VALUES(7,'Hummer',41400)")
        cur.execute("INSERT INTO Cars VALUES(8,'Volkswagen',21600)")
except:
    pass
