我的程序中有两个网格表，但我只能看到一个没有滚动条。用Boxsizer在网上看到过，但是试过之后gird的窗口变得很小。表不清楚。下面是代码。我对Boxsizer和滚动条控件的设置关系不熟悉。

import wx
import wx.grid
class TestTable(wx.grid.PyGridTableBase):#
    def __init__(self):
        wx.grid.PyGridTableBase.__init__(self)
        self.data = { (1,1) : 'Here',
        (2,2) : 'is',
        (3,3) : 'some',
        (4,4) : 'data',
        }
        self.odd=wx.grid.GridCellAttr()
        self.odd.SetBackgroundColour('sky blue')
        self.odd.SetFont(wx.Font(10, wx.SWISS, wx.NORMAL, wx.BOLD))
        self.even=wx.grid.GridCellAttr()
        self.even.SetBackgroundColour('sea green')
        self.even.SetFont(wx.Font(10, wx.SWISS, wx.NORMAL, wx.BOLD))
    # these five are the required methods
    def GetNumberRows(self):

        table = TestTable()
        grid.SetTable(table, True)
        # second grid
        le = TestTable()
        grid.SetTable(le, True)
app = wx.PySimpleApp()
frame = TestFrame()
frame.Show()
app.MainLoop()
