This code equally stretches each column so that they fit the table’s width. table->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch); Docs: QHeaderView::setSectionResizeMode See resize modes here.
That turned out to be easier than I thought. Simply adding this row makes the selection to be by row instead of cell. self.tv.setSelectionBehavior(QAbstractItemView.SelectRows)
I managed to find a workaround for this issue, you just need to hide the table before calling resizeColumnsToContents(). For an example: tableResult->setVisible(false); tableResult->resizeColumnsToContents(); tableResult->setVisible(true);
If you are using Qt 5, QHeaderView::setResizeMode() is no longer available. Instead, you can use QHeaderView::setSectionResizeMode(): ui->tableView->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch); Or just call it for every column: for (int c = 0; c < ui->tableView->horizontalHeader()->count(); ++c) { ui->tableView->horizontalHeader()->setSectionResizeMode( c, QHeaderView::Stretch); }
cmannett85’s recommendation is a good one. Read the docs about a dozen times. Then, if performance and memory issues are your primary concern and you think you can out-perform the QTableWidget implementation, then a QTableView interface on top of a QAbstractTableModel or QStandardItemModel is what you’re looking for. Since you’re new to Qt’s model-view architecture, … Read more
For Qt versions < 5 QHeaderView *verticalHeader = myTableView->verticalHeader(); verticalHeader->setResizeMode(QHeaderView::Fixed); verticalHeader->setDefaultSectionSize(24); For Qt versions >= 5 use QHeaderView *verticalHeader = myTableView->verticalHeader(); verticalHeader->setSectionResizeMode(QHeaderView::Fixed); verticalHeader->setDefaultSectionSize(24); If that function doesn’t apply to vertical headers, you likely will have to call setRowHeight() every time you add a new row.
Use table->verticalHeader()->hide(); to get the vertical header and hide it, and table->setSelectionBehavior(QAbstractItemView::SelectRows); to make QTableView only select whole rows. You may also want to specify the selection mode.

The method selectionModel() return a QItemSelectionModel. You can use QItemSelectionModel class to check/change/other selection(s) Example: QItemSelectionModel *select = table->selectionModel(); select->hasSelection() //check if has selection select->selectedRows() // return selected row(s) select->selectedColumns() // return selected column(s) …
