pygtk表格 

table = gtk.Table(rows=1, columns=1, homogeneous=False)

第一个参数是表格的行数，第二个是表格的列数，homogeneous表格的box的大小是否调整成最大的widget的大小。rows=2且colunms=2的表格如下：

 

0               1              2

0+----------+----------+

|

|

|

1+----------+----------+

|

|

|

2+----------+----------+

在表格中放置widget

 

table.attach(child, left_attach, right_attach, top_attach, bottom_attach,
xoptions=EXPAND|FILL, yoptions=EXPAND|FILL, xpadding=0, ypadding=0)

假设你要在一个2*2的表格中，在首行放置widget,则 left_attach = 0,right_attach = 2, top_attach = 0,bottom_attach = 1。x和y字义了放置的选项，可以使用or定义多选项:
FILL表示如果表格单元比widget大一点，widget 在单元中将填充整个房间

SHRINK 表示如果表格widget被分配小些的空间，widgets在窗体的底部被放置和消失

EXPAND导致表格单元被扩展到表格的余下空间

 set_row_spacing() 和set_col_spacing() 在特定的行或列中加空间

table.set_row_spacing(row, spacing)
table.set_col_spacing(column, spacing)

在所有行列中设置加固定空间

table.set_row_spacings(spacing)

table.set_col_spacings(spacing)
此外，在win下关闭窗口要注意:

1.关闭按钮的事件如下:

button.connect_object("clicked", gtk.Widget.destroy,window)

2.编写一个destroy的处理函数

 def close_application(self, widget):
  gtk.main_quit()

3.在__init__中设置处理窗口destroy的函数

  window.connect("destroy", self.close_application)

我们将上面的代码修改后可以成功退出窗口
