编辑 QTableWidget PyQt5

  • 772

该表有2列。растянуть второй在剩下的时间里有可能吗？

我注意到在你可以写的列名下（在Date和下Title），是否有可能，例如，减少这两个单元格的高度和убрать возможность вводить туда текст？

PS：用于进一步添加行的表格。如果他们离开屏幕，会出现一个滚动条吗？

非常感谢提前

正面

    您没有使用布局，所以我建议不要拉伸，而是设置您需要的列的宽度

    self.table_w.setColumnWidth(1, 330)

    self.table.setEditTriggers(QtWidgets.QAbstractItemView.NoEditTriggers)
