How to word wrap text in the rows and columns of a QTableWidget?

[TheIndependentAquarius]

I tried:

QTableWidget *j = new QTableWidget (10000, 5, centralWidget);
    j->setColumnWidth (0, 500);
    j->setColumnWidth (1, 30);
    j->setColumnWidth (2, 30);
    j->setColumnWidth (3, 320);
    j->setColumnWidth (4, 310);
 
    j->setWordWrap (true);

QTableWidget *j = new QTableWidget (10000, 5, centralWidget);
    j->setColumnWidth (0, 500);
    j->setColumnWidth (1, 30);
    j->setColumnWidth (2, 30);
    j->setColumnWidth (3, 320);
    j->setColumnWidth (4, 310);

    j->setWordWrap (true);

To copy to clipboard, switch view to plain text mode 

Also tried resizeColumnsToContents and resizeRowsToContents, but failed.

If the text is longer than the set width, I want the sentence to get break down.
Currenty, the lengthy part of the sentence just doesn't get shown.
