我在python中使用了一个名为tkintertable的库，它本质上使我能够有效地将表添加到tkinter应用程序中。我正在尝试设置6个不同的表，其中6个图表与此框架（基本上是我的主页）中的每个表一起使用，但我对tkinter来说是全新的，因此在组织它时遇到了一些问题，目前我的代码如下所示：

import tkinter as tk
from tkintertable import TableCanvas, TableModel

class MainApplication(tk.Tk):
    """Main application class"""
    def __init__(self, *args,**kwargs):
        tk.Tk.__init__(self)
        self._frame = None
        self.switch_frame(TickerInput, None)

    def switch_frame(self, frame_class, ticker):
        """Destroys current frame and replaces it with a new one."""

        if ticker is not None:
           new_frame = frame_class(self, ticker) 
        else:
            new_frame = frame_class(self)

        if self._frame is not None:
            self._frame.destroy()

        self._frame = new_frame
        self._frame.grid()

class TickerInput(tk.Frame):
    """Ticker input page that allows input of ticker and redirects to main indicator page"""
    def __init__(self, master):
        tk.Frame.__init__(self, master, background="#212020")

        # Centers the frame
        self.master.columnconfigure(0, weight=1)
        self.master.rowconfigure(0, weight=1)

        ticker_label = tk.Label(self, text="Enter ticker..")
        ticker_label.grid(row=0, column=1, columnspan=2)

        ticker_input = tk.Entry(self, width=35)
        ticker_input.grid(row=0, column=3)

        button = tk.Button(self, text="Search", command=lambda: master.switch_frame(Indicator, ticker_input.get()))
        button.grid(row=1, column=1, columnspan=3)

class Indicator(tk.Frame):
    """Indicator page that shows the indicators and whether its a buy or sell"""
    def __init__(self, master, ticker):
        tk.Frame.__init__(self, master)
        self.ticker = ticker
        self.master.columnconfigure(0, weight=0)
        self.master.rowconfigure(0, weight=1)
        self.columnconfigure(0, weight=1)
        self.rowconfigure(0, weight=1)

        button = tk.Button(self, text="Go Back", command=lambda: master.switch_frame(TickerInput, None))
        button.grid(column=0, row=0)

        ticker_label = tk.Label(self, text=("Current Ticker: " + self.ticker))
        ticker_label.grid(column=1, row=0)

        tableOne = Table(self)
        tableOne.grid(column=0, row=1)
        tableOne.createTable()

        # tableTwo = Table(self)
        # tableTwo.createTable()

class Table(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        self.master = master

    def createTable(self):
        data = {'rec1': {'col1': 99.88, 'col2': 108.79, 'label': 'rec1'},
       'rec2': {'col1': 99.88, 'col2': 108.79, 'label': 'rec2'}
       } 

        model = TableModel()
        table = TableCanvas(self.master, model=model, data=data)
        table.show()

        return table

if __name__ == "__main__":
    app = MainApplication()
    app.title("Indicator Trading Confirmation Tool")
    app.geometry("1920x1080")
    app.config(background="#121212")
    app.mainloop()

这是gui

为什么我的返回按钮卡在table上，如果我把它放在另一排，并且把我的体重设置为1，这应该将它们分开50%正确？还有，组织这两个网格/代码的最佳方式是什么，以确保gui有6个相等的表/图表，3个在左边，3个在右边？非常感谢。
