I\'m developing a computer application with PySide and I\'m using the QTableWidget. Let\'s say my table has 3 columns, but the data they contain is very different,

Answer 1

PyQt4

header = self.table.horizontalHeader()
header.setResizeMode(0, QtGui.QHeaderView.Stretch)
header.setResizeMode(1, QtGui.QHeaderView.ResizeToContents)
header.setResizeMode(2, QtGui.QHeaderView.ResizeToContents)
header.setResizeMode(3, QtGui.QHeaderView.Stretch)

PyQt5

header = self.table.horizontalHeader()       
header.setSectionResizeMode(0, QtWidgets.QHeaderView.Stretch)
header.setSectionResizeMode(1, QtWidgets.QHeaderView.ResizeToContents)
header.setSectionResizeMode(2, QtWidgets.QHeaderView.ResizeToContents)
header.setSectionResizeMode(3, QtWidgets.QHeaderView.Stretch)
