import wx import wx.grid import generictable data = (("Bob", "Dernier"), ("Ryne", "Sandberg"), ("Gary", "Matthews"), ("Leon", "Durham"), ("Keith", "Moreland"), ("Ron", "Cey"), ("Jody", "Davis"), ("Larry", "Bowa"), ("Rick", "Sutcliffe")) colLabels = ("Last", "First") rowLabels = ("CF", "2B", "LF", "1B", "RF", "3B", "C", "SS", "P") class SimpleGrid(wx.grid.Grid): def __init__(self, parent): wx.grid.Grid.__init__(self, parent, -1) tableBase = generictable.GenericTable(data, rowLabels, colLabels) self.SetTable(tableBase) class TestFrame(wx.Frame): def __init__(self, parent): wx.Frame.__init__(self, parent, -1, "A Grid", size=(275, 275)) grid = SimpleGrid(self) if __name__ == '__main__': app = wx.PySimpleApp() frame = TestFrame(None) frame.Show(True) app.MainLoop()

效果如下：
