Question

我有一个文本文件，该文件根据文件名存储数据。我这样做了，因此用户可以选择他们要搜索的文本文件，并且根据他们选择的内容，该文件的数据将显示在该文件的正确标题下。问题在于，由于数据的大小可能会有所不同，因此我似乎无法使标题与文件中的数据保持一致。

我尝试放置文本文件并将其逐行分割，然后为要显示的每一行创建一个标签，但这永远不会与标题对齐，因为标签内的信息实际上可以是任何大小。为了尝试修复它，我尝试将每一行拆分为单独的元素，以为每个元素创建一个标签，但无法正常工作。

    searchWindow.mainloop()
searchPage()

我希望它读为：

ID姓氏电话号码...

000雅各布·彼得森07793 ...

但是，它的读法是：

ID姓氏电话号码...

000，Jacob，Peterson，077943 ...

因此，它显然没有对齐（我无法按预期格式进行格式化，但第一个示例应对齐）。
