推荐答案

您试图隐藏的选定单元格周围的虚线边框看起来像是一个焦点矩形.任何给定的单元格都可以具有焦点并且不会同时被选中，反之亦然.如果您希望此边框不被绘制，请使用项目委托.在那里您可以在绘制之前从项目的状态中删除 State_HasFocus 样式.请参阅下面的示例，了解如何执行此操作，它是 C++，如果您在将其转换为 python 时遇到问题，请告诉我

It looks like this dotted border around selected cell you're trying to hide is a focus rectangle. Any given cell can have focus and not be selected at the same time and vice-versa. If you want this border to not get painted use an item delegate. There you can remove State_HasFocus style from the item's state before painting it. Pls, see an example below on how to do this, it's c++, let me know if you have troubles converting it to python

// custom item delegate class
class NoFocusDelegate : public QStyledItemDelegate
{
protected:
    void paint(QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const;
};

void NoFocusDelegate::paint(QPainter* painter, const QStyleOptionViewItem & option, const QModelIndex &index) const
{
    QStyleOptionViewItem itemOption(option);
    if (itemOption.state & QStyle::State_HasFocus)
        itemOption.state = itemOption.state ^ QStyle::State_HasFocus;
    QStyledItemDelegate::paint(painter, itemOption, index);
}
...
// set the item delegate to your table widget
ui->tableView->setItemDelegate(new NoFocusDelegate());
