使用python的wx.grid，你如何合并列？

这是我想它的样子，与列合并。

我想在每个三列合并列昨天和今天。所以昨天会高于股票，波动和现金。然后同样适用于今天。我找到了一个叫做wx.grid.SetColSize(self, int col, int width)的函数，但它没有任何作用。有谁知道如何做到这一点？

这是我的代码。

import wx 
import wx.grid as gridlib 

class MyForm(wx.Frame): 
    def __init__(self): 
     """Constructor""" 
     wx.Frame.__init__(self, parent=None, title="Strategies' Allocations") 
     self.panel = wx.Panel(self) 

     button_refresh = wx.Button(self.panel, id=wx.ID_ANY, label='Refresh') 
     button_refresh.Bind(wx.EVT_BUTTON, self.refresh) 

     self.myGrid1 = gridlib.Grid(self.panel) 
     self.myGrid1.CreateGrid(2, 6) 

     self.myGrid1.SetRowLabelSize(60) 
     self.myGrid1.SetRowLabelValue(0, "") 
     self.myGrid1.SetRowLabelValue(1, "ABRVXX") 

     for i in range(6): 
      self.myGrid1.SetColSize(i, 60) 

     self.myGrid1.SetColLabelValue(0, "") 
     self.myGrid1.SetColLabelValue(1, "Yesterday") 
     self.myGrid1.SetColLabelValue(2, "") 
     self.myGrid1.SetColLabelValue(3, "") 
     self.myGrid1.SetColLabelValue(4, "Today") 
     self.myGrid1.SetColLabelValue(5, "") 

     self.myGrid1.SetCellValue(0, 0, "Equity") 
     self.myGrid1.SetCellValue(0, 1, "Volatility") 
     self.myGrid1.SetCellValue(0, 2, "Cash") 
     self.myGrid1.SetCellValue(0, 3, "Equity") 
     self.myGrid1.SetCellValue(0, 4, "Volatility") 
     self.myGrid1.SetCellValue(0, 5, "Cash") 

     self.myGrid1.SetColLabelAlignment(wx.ALIGN_CENTRE, wx.ALIGN_CENTRE) 
     self.myGrid1.SetDefaultCellAlignment(wx.ALIGN_CENTRE, wx.ALIGN_TOP) 
     # ******************************* #

不知道你的意思。你能用网格中的数据给你一些截图吗？ – Igor

@Igor我添加了一个截图来显示我想要的。 –

快速而肮脏的方法是转储列标签SetColLabelSize(0)并将标题添加为单元格。
然后调整单元跨度为SetCellSize()的那些单元格。
下面我改变了myGrid1，但不是myGrid2。

因为我正在努力做到这一点，所以完成了这项工作。谢谢您的帮助。 –

@AlexF在您对两个答案进行编辑之后，我已添加回调整图像。如果仍然存在隐私问题，请随时重新编辑。 –

这太好了。对那些需要它的人仍然很有帮助，但保持隐私。感谢您的包容。 –

这不会是特别简单的，但我认为你应该达到你想要的东西从wxGridCellAttrProvider定义一个类派生并重写其GetColumnHeaderRenderer()方法返回一个“什么都不做” wxGridColumnHeaderRenderer你想要的列合并，并为其他标准渲染器（由基类GetColumnHeaderRenderer()返回）。然后你只需要在你的表对象上用你自定义的属性提供者对象调用SetAttrProvider()。

看看在wxPython中演示的GridLabelRenderer样品。这是根据wx.lib.mixins.gridlabelrenderer中的类为网格行和列绘制自定义标签的示例。使用这些类可以非常容易地根据需要绘制标签。您只需要重写相应的Draw方法。

正如@RobinDunn所建议的那样，这里是一个使用GridLabelRenderer的版本（排序），它不像第一次看起来那么复杂。
但是，它确实有一些奇怪的地方。
请注意使用l和r来存储rect.left和rect.right。
这样做是因为如果你调整rect.left，right.right也可以调整，而不需要你这样做。
我认为这是因为rect有一个大小，所以如果你调整1个元素，另一个补偿。
还要注意，您必须声明空白列标题，否则它们将恢复为标准的“A，B，C，D .....”序列。
