I made a program to get a value from user and display data in a table equal to the user input, my problem is the data is not updated in the columns and not displayed whatever the data is retrieved and printed, I searched on it and I get nothing

def show_data(self,panel_value):
    try:
        for item in self.get_children():
            self.delete(item)
        Current_data = db_file("database.db").get_data(panel_value)
        print(Current_data)
        self.insert_data(DB_data=Current_data)
        self.update()
    except Exception as e:
        print(f"{e}")
        
def insert_data(self,DB_data):
    for row in DB_data:
        self.insert("", "end", values=row)
        print("Row inserted:", row)

the database body

'( "Floor_Level" text, "Panel_name" text, "Demand_load" float, "Load_Current" float, "Safety_Factor" float, "CB_Type" text, "CB_Rating" integer, "No_of_cables" integer, "No_of_Cores" text, "Derating_Factor" float, "Incoming_Cable" integer, "Cable type" text, "ECC" text, "Length" float, "VD_PER" float, "Acc_VD" float, "SC_PER" float )

the data sample:
