python - 选项卡式 tkinter GUI 中小部件的均匀水平间距

Question

我有一个使用 tkinter 编写的带有 gui 的小程序。gui 有三个不同行数的选项卡，如下图所示。

困扰我的是选项卡底部的空白区域，行数较少。

是否可以将小部件水平均匀分布？

这是使事情到位的代码：

#GUI
root = Tk()
root.title("Mancha de inundação")
root.resizable(False, False)

#tab settings
tabControl = ttk.Notebook(root)

tab1 = ttk.Frame(tabControl)
tab2 = ttk.Frame(tabControl)
tab3 = ttk.Frame(tabControl)

tabControl.add(tab1, text='Passo 1')
tabControl.add(tab2, text='Passo 2', state="disabled")
tabControl.add(tab3, text='Passo 3',  state="disabled")

tabControl.pack(expand=1, fill="both")

#Tab1
#lat long
label_y = Label(tab1, text="Latitude:")
label_y.grid(row=1, column=0, sticky='W', padx=10, pady=10)

label_x = Label(tab1, text="Longitude:")
label_x.grid(row=2, column=0, sticky='W', padx=10, pady=10)

entry_y = Entry(tab1, width=8)
entry_y.grid(row=1, column=1, sticky='E', padx=10, pady=10)

entry_x = Entry(tab1, width=8)
entry_x.grid(row=2, column=1, sticky='E', padx=10, pady=10)

#h v
