'我不知道为什么搜索按钮不起作用，搜索按钮应该在 Excel 中搜索文本框中的 id，然后如果找到，则应该出现一个表示成功的框，但是当我按下搜索按钮时什么也没有发生，这是整个代码，我有点新，我不太了解Python。

您的搜索功能不正确。您基本上直接将字符串值与 xl.cell.read_only(sheet,column = ['A'] 进行比较，这没有意义。您可以尝试下面的搜索功能。

def search():
    file = xl.load_workbook('Data.xlsx')
    sheet = file["Sheet1"]
    search_res = Search_Entry.get()
    
    for row in sheet.iter_rows(values_only=True):
        if search_res in row:
            YesText=customtkinter.CTkLabel(master=app,text="yes",font=FontMed)
            return
