对于 Qt版本< 5

QHeaderView *verticalHeader = myTableView->verticalHeader();
verticalHeader->setResizeMode(QHeaderView::Fixed);
verticalHeader->setDefaultSectionSize(24);

对于 Qt版本> = 5 ，使用

QHeaderView *verticalHeader = myTableView->verticalHeader();
verticalHeader->setSectionResizeMode(QHeaderView::Fixed);
verticalHeader->setDefaultSectionSize(24);

如果该功能不适用于垂直标题，则每次添加新行时，您可能都必须调用setRowHeight().

If that function doesn't apply to vertical headers, you likely will have to call setRowHeight() every time you add a new row.
