Question

我正在使用Tkinter来对齐屏幕文本。我未能正确对齐要显示的文本。目前，这是在24英寸显示器上显示的，我无法部分显示文本一直到屏幕右侧。我已经尝试过

sticky=E

但是它没有将文本向右移动。Screen Image

您需要做的是为中心栏设置权重。权重用于告诉列/行扩展特定的速率。

将此行添加到win = Tk()下：

win.columnconfigure(1, weight=1)

然后将标签中的列更改为以下内容。

Label(win,text="%").grid(row=2,column=1)
Label(win,text="PCS").grid(row=2,column=2)
Label(win,text="").grid(row=3,sticky=W)

Label(win,text="Target:").grid(row=4)
Label(win,text="75").grid(row=4,column=1)
Label(win,text=TARGET_DISPLAY).grid(row=4,column=2)
Label(win,text="").grid(row=5,sticky=W)

Label(win,text="Actual:").grid(row=6)
Label(win,textvariable=ACTUAL_VALUE).grid(row=6,column=2)
Label(win,textvariable=Efficiency_VALUE).grid(row=6,column=1)

这应将您应该在此处的所有标签移到最右边，然后将中间标签移到屏幕的百分之一。
