Thanks for the response, but i saw that in the documentation before asking, and it's not what i'm looking for. The columns for my purpose do not need to be fully stretched out, i just need the last column in the view to auto-stretch if there is space for it to take up. Since QTableWidget does not by default support HTML, i had attempted two methods into getting it to display HTML. The first was subclassing QItemDelegate and QTableWidgetItem. The other was setting a QLabel as a table cell's widget. However, both of them have undesirable consequences which i have been trying to solve. The common undesirable consequence is that both attempts do not give the proper (i believe) size hints for the table cell, so double-clicking on the row's or column's edge causes an inaccurate resize.

In attempting to detect if a column has been resized by the user, i thought 

   tableWidget.__class__.columnResized = self.columnResized

would help, but it didn't. The reason why i need to detect if the user resized the column is so i can resize all the rows.
