I'm creating python app using relatively big SQL database (250k rows). Application needs GUI where most important part of it would be to present results of SQL queries.
So I'm looking for a best way to quickly present data in tables in GUI.
Most preferably I'd be using wx - as it has seamless connection to main application I'm working with. And what I need is least effort between SQL query a and populating GUI table. 
I used once wx.grid, but it seemed to be limited functionality. Also I know of wx.grid.pygridtablebase - what is the difference?
What would be easiest way to do this?
You could use wx.grid or one of the ListCtrls. There's an example of a grid with 100 million cells in the wxPython demo that you could use for guidance on projects with lots of information. For ListCtrls, you would want to use a Virtual ListCtrl using the wx.LC_VIRTUAL flag. There's an example of that in the demo as well.
