问题将滚动条添加到TKINTER中的画布

Question

我一直在关注许多有关如何在画布中添加滚动条的教程，但是，我遇到了许多无法解决的问题。起初，我尝试直接将滚动条添加到帆布中，但是将卷轴涂成灰色，如下所示。

def student_menu():
    csr = db.cursor()
    student_window = tk.Toplevel(root)
    student_window.title("Student Menu")
    student_window.geometry("700x500")

    label = tk.Label(student_window, text = "Welcome to the student menu")
    label.grid(row = 0, column = 0, columnspan = 2)

    canvas = tk.Canvas(student_window, width = 700, height = 500)
    canvas.grid(row = 1, column = 0, columnspan = 2)
    scrollbar = tk.Scrollbar(student_window, orient = "vertical", command = 
    canvas.yview)
    scrollbar.grid(row = 1, column = 2, sticky = "ns")
    canvas.configure(yscrollcommand = scrollbar.set)

    csr.execute("USE miniia")
    csr.execute("SELECT * FROM students")
    data = csr.fetchall()
    i = 0
    for row in data:
        for j in range(len(row)):
            e = tk.Entry(canvas, width = 20)
            e.grid(row = i + 1, column = j)
            e.insert(0, row[j])
        i += 1
    csr.close()

尝试尝试用相关表嵌入画布中的框架，然后将入口小部件表嵌入其中以滚动。但是，桌子上出现了一个奇怪的灰色盒子，否则在下面显示了正确的滚动轮和功能。

相关代码：

def student_menu():
    csr = db.cursor()
    student_window = tk.Toplevel(root)
    student_window.title("Student Menu")
    student_window.geometry("700x500")

    label = tk.Label(student_window, text = "Welcome to the student menu")
    label.grid(row = 0, column = 0, columnspan = 2)

    frame = tk.Frame(student_window)
    frame.grid(row = 1, column = 0, columnspan = 2)

    csr.execute("USE miniia")
    csr.execute("SELECT * FROM students")
    data = csr.fetchall()
    i = 0
    for row in data:
        for j in range(len(row)):
            e = tk.Entry(frame, width = 20)
            e.grid(row = i + 1, column = j)
            e.insert(0, row[j])
        i += 1
    csr.close()
    
    canvas = tk.Canvas(student_window, width = 700, height = 500)
    canvas.grid(row = 1, column = 0, columnspan = 2)
    canvas.create_window(0, 0, anchor = 'nw', window = frame)
    frame.update_idletasks()
    canvas.config(scrollregion = canvas.bbox('all'))
    scrollbar = tk.Scrollbar(student_window, orient = 'vertical', command = 
    canvas.yview)
    scrollbar.grid(row = 1, column = 3, sticky = 'ns')
    canvas.config(yscrollcommand = scrollbar.set)

我不知道如何从这里继续。
