你可以使用 `button.config(borderwidth=2)` 和 `button.config(relief="groove")` 来替换 `button.config(relief="sunken")` 和 `button.config(relief="raised")`。这样当你鼠标进入按钮时，它的外观将会变化。修改后的代码如下：

def load_excel(self, filename,menu_label):
    self.la=menu_label
    self.workbook = xl.load_workbook(filename)
    self.sheet_names = self.workbook.sheetnames
    
    # 清空左侧面板
    for widget in self.panel_left.winfo_children():
        widget.destroy()
    
    # 添加工作表按钮
    style = ttk.Style()
    style.configure('my.TButton', font=('Arial', 10))
    style.map('my.TButton', background=[('active', '#007FFF')])
    
    for i, sheet_name in enumerate(self.sheet_names):
        button = ttk.Button(self.panel_left, text=sheet_name, command=lambda name=sheet_name: self.show_sheet(name),
                             style='my.TButton')
        button.used = False
        button.grid(row=i, column=0, sticky="ew", padx=2, pady=2)
        button.config(borderwidth=2)
        button.config(relief="groove")
        
        def mark_used(button):
            # 将按钮的标记设置为“已使用”
            button.used = True
            # 更改按钮的背景颜色
            button.configure(bg="gray")
        
        # 绑定按钮的点击事件
        button.bind("<Button-1>", lambda event, button=button: mark_used(button))
        button.bind("<Enter>", lambda event, button=button: button.config(relief="sunken"))
        button.bind("<Leave>", lambda event, button=button: button.config(relief="raised"))

这样应该可以解决你的问题。
