[Tkinter] Different rows colours in treeview tkinter

[Krissstian]

I have a treeview wich is populated from an sql DB:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

def fetch_data():     con = pymysql.connect(host='localhost', user='root', password='*', database='*')     cur = con.cursor()     cur.execute('select  Var60,'                 'Var61, Var62, Var63, Var64, Var65, Var66, Var67, Var68, Var69, Var70, operator from prices order by crt desc')     rows = cur.fetchall()       if rows != 0:         self.totalrecord.set(len(rows))         table.delete(*table.get_children())           for row in rows:             if self.Var79 == 'A':                 table.insert("", END, values=row, tags='Blue')             else:                 table.insert("", END, values=row, tags='White')           con.commit()     con.close()

Treeview:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

style = ttk.Style()        style.configure('Treeview',                        background='white')        style.map('Treeview',                  background=[('selected', 'blue')])          view_frame = Frame(data_frame, bd=5, relief='flat', bg='#D9E9EC')        view_frame.place(x=1, y=25, width=1185, height=300)        x_scroll = Scrollbar(view_frame, orient=HORIZONTAL)        y_scroll = Scrollbar(view_frame, orient=VERTICAL)        table = ttk.Treeview(view_frame, xscrollcommand=x_scroll.set, yscrollcommand=y_scroll.set, columns=(             'Var60',            'Var61', 'Var62', 'Var63', 'Var64', 'Var65', 'Var66', 'Var67', 'Var68', 'Var69', 'Var70'))          x_scroll.pack(side=BOTTOM, fill=X)        y_scroll.pack(side=RIGHT, fill=Y)        table.tag_configure('Blue', background="blue")        table.tag_configure('White', background="white")        x_scroll.config(command=table.xview)        y_scroll.config(command=table.yview)                   table.heading("Var60", text="Var60")        table.heading("Var61", text="Var61")        table.heading("Var62", text="Var62")        table.heading("Var63", text="Var63")        table.heading("Var64", text="Var64")        table.heading("Var65", text="Var65")        table.heading("Var66", text="Var66")        table.heading("Var67", text="Var67")        table.heading("Var68", text="Var68")        table.heading("Var69", text="Var69")                   table['show'] = 'headings'        table.bind('<ButtonRelease-1>', focus)        fetch_data()        table.pack(fill=BOTH, expand=1)

Why for matching criteria (self.Var79) the tags are not blue?

[woooee]

tag = is a tuple.
