如何在 tksheet 中更新 window(table) a table？

Question

Hello friends how can I update the window in tksheet. I have a database.Which connects to Postgresql and pulls out data. In addition, I can choose the date of the data, from which to which.After starting, I select the dates and click on the "Get data" button.The first time is displayed. After the first time, the data is not output to the interface.But it is displayed in the console. You can't select the date a second time and display it on the interface. I think that you need to update the window, if so, as soon as possible.

       def sec_frame(self):
           global date_from1, date_from2
           sec_frame1 = Frame(self.master, background='#21acfc', )
           sec_frame1.pack()

           query_button = tk.Button(sec_frame1, text='Get data', width=200, command=self.get_datas)
           query_button.pack(side=LEFT, padx=50, pady=40)

           date_from1 = DateEntry(sec_frame1, background='#e03aca', font="Helvetica 14", locale='KY')
           date_from1.pack(side=LEFT, padx=50)

           date_from2 = DateEntry(sec_frame1, background='#e03aca', font="Helvetica 14",locale='KY')
           date_from2.pack(side=LEFT)
     
    
        def get_datas(self):
            date1 = date_from.get_date()
            date2 = date_to.get_date()
            query_datas= f"select *from client_info where date_to='{date1}'::date and date_from='{date2}'::date"
            self.cursor.execute(query_datas)
            get_datas = self.cursor.fetchall()
            print(get_datas) #I actually get the data in the console
            try:
                get_datas[0]
            except IndexError:
                messagebox.showerror('some text', 'some text')
    
            lenn = len(get_datas)
            len1 = len(get_datas[0])
            bottom_frame = Frame(self.master, )
            table = Sheet(bottom_frame, page_up_down_select_row=True, column_width=120, startup_select=(0, 1, "rows"),
                          data=[[get_datas[r][c] for c in range(len1)] for r in range(lenn)],
                          height=1000,
                          width=1920
                          )
            table.enable_bindings(("single_select",

                                   "row_select",

                                   "right_click_popup_menu",
                                   "rc_select",
                                   "rc_insert_column",
                                   "rc_delete_column",
                                   "rc_insert_row",
                                   "rc_delete_row",
                                   "hide_columns",
                                   "copy",
                                   ))
            bottom_frame.pack()
            table.pack(side=TOP)

Answer 1

** 非常感谢。你是对的。我这样做了。在sec_frame函数中，我创建了全局变量table、bottom_frame。我在 get_datas 函数中调用了这些全局变量，并向 table table.set_sheet_data(data=[]) 传递了一个空值。每次我第一次点击按钮时，我都会将空数据传递给 table。然后收到的请求再次通过table。 set_sheet_data(data=[......]).并且在bottom_frame的最后，table做了一个pack()**
