我的問題是：輸出應(yīng)該顯示 2 個側(cè)邊欄（第 0 列和第 2 列），其中包含內(nèi)容標(biāo)簽和條目以及一個中央窗口（第 1 列），比中間的其他側(cè)邊欄大得多。但中間的列總是出現(xiàn)在右側(cè)，并且作為一個非常小的框架。請幫忙。我的代碼和圖片：import tkinter as tk, tkinter.ttk as ttkroot = tk.Tk()root.title("THE FRIDGER")root.grid_columnconfigure(0, weight=1)root.grid_rowconfigure(2, weight=1)#prepared datadflt = dict(fg="white", bg="black")pads = dict(pady=4, padx=4)#header frameheader = tk.Frame(root, bg="black")header.grid(row=0, column=0, columnspan=3, sticky="nsew")for i in range(2):    header.grid_columnconfigure(i, weight=1)#header labelstk.Label(header, text="Fridge", **dflt).grid(column=0, row=0, **pads)tk.Label(header, text="Recipes", **dflt).grid(column=1, row=0, **pads)#separators = ttk.Style()s.configure('custom.TSeparator', background='blue')ttk.Separator(root, style='custom.TSeparator').grid(row=1, column=0, columnspan=3, sticky="ew")#left side contentl_content = tk.Frame(root, bg="black")l_content.grid(row=2, column=0, sticky="nsew")tk.Label(l_content, text="Content:", **dflt).grid(column=0, row=0, sticky=tk.W)l_query = tk.Entry(l_content, width=36, relief=tk.FLAT, bg = "white", fg = "black")l_query.grid(column=0, row=1, sticky=tk.W)#right side contentr_content = tk.Frame(root, bg="black")r_content.grid(row=2, column=2, sticky="nsew")tk.Label(r_content, text="Content:", **dflt).grid(column=0, row=2, sticky=tk.W)r_query = tk.Entry(r_content, width=36, relief=tk.FLAT, bg = "white", fg = "black")r_query.grid(column=0, row=3, sticky=tk.W)#middle contentm_content = tk.Frame(root, bg="white")m_content.grid(row=2, column=1, sticky="nsew")tk.Label(m_content, text="This should appear in the middle", **dflt).grid(column=0, row=2,       sticky=tk.W)m_content.grid_columnconfigure(1, weight = 1)root.mainloop()
