title: spreadsheet-like-app in tkinter?
body: <p>Suppose one were to want to build a spread-sheet in tkinter. So one could have (many) cells, most of which would take text entry, but some could be drop-down lists (tkinter comboboxes) etc. </p>
  
  <p>Is that feasible in tkinter for a spreadsheet of any size? (Say 100x10)? Or would that many tkinter Text object and comboboxes etc just be too much handle performance wise? (Or is there some other way to do this other than just gridding many tkinter objects?)</p>
  
  <p>I ask not because I want to do this literally, but because I need to build an app in which users are presented with lots of chunks of information, any of them editable. It's convenient for the user to access those chunks directly (click on the cell) rather than have to pass through some preliminary interface.</p>
