I'd never used the PyGridTableBase to do this before, so I used the
wxPython demo to figure it out. If you check out the GridCustomTable
demo code, you'd probably have gotten it as well. Basically, you
needed to add another class that inherited from wx.grid.Grid that
would use the base you created. Here's the modified code:

<code>

import wx
import wx.grid as gridlib

class TestTable(wx.grid.PyGridTableBase):
    def __init__(self):
        gridlib.PyGridTableBase.__init__(self)
        self.rowLabels = ["uno", "dos", "tres", "quatro", "cinco"]
        self.colLabels = ["homer", "marge", "bart", "lisa", "maggie"]


    def GetNumberRows(self):
        return 5

    def GetNumberCols(self):
        return 5

    def IsEmptyCell(self, row, col):
        return False

    def GetValue(self, row, col):
        return "(%s,%s)" % (self.rowLabels[row], self.colLabels[col])

    def SetValue(self, row, col, value):
        pass

    def GetColLabelValue(self, col):
        return self.colLabels[col]

    def GetRowLabelValue(self, row):
        return self.rowLabels[row]

class CustTableGrid(gridlib.Grid):
    def __init__(self, parent):
        gridlib.Grid.__init__(self, parent, -1)

        table = TestTable()

        # The second parameter means that the grid is to take
ownership of the
        # table and will destroy it when done.  Otherwise you would
need to keep
        # a reference to it and call it's Destroy method later.
        self.SetTable(table, True)

        self.SetRowLabelSize(0)
        self.SetMargins(0,0)
        self.AutoSizeColumns(False)

class TestFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="Grid Table",
                          size=(500,200))
        panel1 = wx.Panel(self, -1)
        panel2 = wx.Panel(self, -1)
        hbox1 = wx.BoxSizer(wx.HORIZONTAL)

        hbox1.Add(panel1, 1, wx.EXPAND | wx.ALL, 3)
        hbox1.Add(panel2, 1, wx.EXPAND | wx.ALL, 3)


        table = CustTableGrid(panel2)
        tblSizer = wx.BoxSizer(wx.VERTICAL)
        tblSizer.Add(table, 1, wx.ALL|wx.EXPAND, 5)
        panel2.SetSizer(tblSizer)

        self.SetSizer(hbox1)

app = wx.PySimpleApp()
frame = TestFrame()
frame.Show()
app.MainLoop()

</code>
