You can find out column from QModelIndex in createEditor, setEditorData, setModelData and do different thing in different cases.

I see in the documentation of Qtablewidget that exist a method setcellwidget(...), whats's the difference between use this or delegate??
Thank you for your reply

Hi,

setCellWidget sets a specific widget to be displayed to a specific cell.

The delegate provides custom display features and editor widgets. So i.e. you don't have to set a widget on every cell, the view will use the delegate to create the appropriate editor.
