[FIXED] Trying to wrap text to fit in qtablewidget column

Issue

I am working on a GUI using pyqt and the QTableWidget. Some rows in the table widget have text which is quite lengthy and I've been struggling to find a way to set a fixed column length for specific columns and then wrap the text to fit that column size no matter the text length.

I searched for solutions online, and while I saw one example addressing such an issue I was unable to implement it into my table widget. I had hoped there'd be a table widget function which does this but there isn't.

Help with this would be appreciated.

The 'Description' column in the table below should be shortened and the text made to wrap and fit a fixed size.

Thank you.

Solution

You may need to force your table widget to resize its rows by calling QTableWidget.resizeRowsToContent.

You can do it automatically whenever the column has been resized with:

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