我一直在尝试在GUI中使用DataFrames，但遇到了一些麻烦，这确实很烦人。我的代码可以运行，但是我看不到要在我的GUI中显示DataFrame的内容。我已经创建了网格和样式，但不会提取数据。
能帮我看看我在想什么。

我本来是用tkinter来构建它的，但是我感到非常沮丧，然后搬到了wxglade。现在，代码开始运行，并且gui显示以及数据表似乎丢失了数据。
失望...猜测您必须是C＃程序员才能在这里获得任何帮助，因为python社区似乎是如此有限。对于任何想知道我已经阅读，观看和观看过该区域的视频的人，在尝试解决该问题时我都收到了一些错误报告，但是在逐步解决问题时似乎总是回到这个问题上。
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
（我不再抛出此错误，但是网格仍然无法初始化）
再次...任何帮助将不胜感激
答案 0 :(得分：0)
使用“ GridTableBase”作为网格名称是一个非常奇怪的选择。
无论如何，在创建包括网格的框架后：
self.table = DataTable(df)
self.frame.GridTableBase.SetTable(self.table, takeOwnership=True)
wxPython的网格演示GridCustTable.py或GridHugeTable.py应该有足够的示例来创建虚拟网格。
