python - Pandas 数据框导入到 WxGlade GUI

问题描述

我一直在尝试在 GUI 中使用 DataFrame，但我遇到了一些非常烦人的麻烦。我的代码运行，但我只是看不到让我的 DataFrame 在我的 GUI 中显示的内容。我已经创建了网格和样式，但它不会提取数据。

你能帮我看看我错过了什么吗？

我最初是用 tkinter 构建的，但我非常沮丧并转向 wxglade。现在代码运行并且gui显示的数据表似乎缺少数据。

失望...猜你必须是 C# 程序员才能在这里获得任何帮助，因为 python 社区似乎如此有限。对于任何想知道我已经阅读、查看和观看该区域的视频的人来说，我在尝试解决这个问题时收到了几个错误报告，但在逐步解决课程问题时似乎总是回到这个问题。

  File "This code", line 66, in __do_layout
    sizer_7 = wx.grid.MyTable(self.ExcelSheet1)
TypeError: wx._grid.MyTable represents a C++ abstract class and cannot be instantiated

（我不再抛出这个错误，但网格仍然没有初始化）

再次......任何帮助将不胜感激
