      Description

      main.c++ which will reproduce the bug:

      #include <QApplication>

      #include <QTableView>

      #include <QHeaderView>

      int main(int argc, char** argv)

      {

          QApplication app(argc, argv);

          auto* view = new QTableView;

          class Model: public QAbstractItemModel {

          public:

              QModelIndex index(int row, int col, const QModelIndex& index) const override

              {

                  if (!index.isValid() && row == col && row == 0) return createIndex(0, 0);

                  return {};

              }

              QModelIndex parent(const QModelIndex& index) const override { return {};}

              int rowCount(const QModelIndex& parent) const override

              {              if (!parent.isValid()) return 1;              else return 0;         }

              int columnCount(const QModelIndex& parent) const override
              {            if (!parent.isValid()) return 1;           else return 0;        }
              QVariant data(const QModelIndex& index, int role) const override

              {

                  if (role == Qt::DisplayRole && index.isValid())

                      return tr("The data of items in models are assigned an ItemDataRole;"

                                "each item can store a QVariant for each role.");

                  return {};

              }

          };

          

          view->setTextElideMode(Qt::ElideMiddle);

          view->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);

          view->setModel(new Model);

          view->show();

          return app.exec();

      }

      The text may display in the cell:

      The data of i...s in models ...

      The data of items in ...

      The ellipsis always appear at right if space is unavailable, and ellipsis at middle may not appear.
