我无法将列隐藏在ObjectListView (FastListView)中

import wx
from ObjectListView import ObjectListView, ColumnDefn

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="ObjectListView Demo")

        # 创建ObjectListView控件
        self.list_ctrl = ObjectListView(self, style=wx.LC_REPORT|wx.SUNKEN_BORDER)

        # 绑定数据源
        self.list_ctrl.SetObjects(data)

        # 设置列定义
        self.list_ctrl.SetColumns([
            ColumnDefn("列1", "left", 100, "attr1"),
            ColumnDefn("列2", "left", 100, "attr2"),
            ColumnDefn("列3", "left", 100, "attr3")
        ])

        # 隐藏第二列
        self.list_ctrl.HideColumn(1)

        # 布局界面
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.list_ctrl, 1, wx.EXPAND)
        self.SetSizer(sizer)

# 示例数据
data = [
    {"attr1": "值1", "attr2": "值2", "attr3": "值3"},
    {"attr1": "值4", "attr2": "值5", "attr3": "值6"}
]

app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
