试图包装文本以适应 qtablewidget 列

Question

我正在使用 pyqt 和 QTableWidget 开发 GUI。 table 小部件中的某些行的文本很长，我一直在努力寻找一种方法来为特定列设置固定的列长度，然后将文本换行以适合该列大小，而不管文本长度如何.

我在网上搜索了解决方案，虽然我看到了一个解决此类问题的示例，但我无法将其实施到我的 table 小部件中。我曾希望有一个 table 小部件功能可以执行此操作，但没有。

我们将不胜感激。

应缩短下面 table 中的 'Description' 列，并使文本换行并适合固定大小。

谢谢。

您可能需要通过调用 QTableWidget.resizeRowsToContent.

强制 table 小部件调整其行的大小

您可以在调整列大小时自动执行此操作：

self.tableWidget.horizontalHeader().sectionResized.connect(self.tableWidget.resizeRowsToContents)
