After hiding the header in the qtablewidget, the left and top borders display abnormally

[John Van]

The right and bottom borders display normally, but the left and top borders disappear.

Those are the gridlines, it is intended this way.

@Tink Thanks for your reply.
Is there a way to display the upper left grid line as well?

Hi,

What about customizing the items? Something like this:

QTableWidget::item
{
	border: 1px solid white;
}

But this will change all items.

Without this stylesheet:

With this stylesheet:

Note: this is not the grid line, but the items' borders, so it's a workaround.

An actual solution would probably require setting a margin for whatever contains the view, I couldn't find out how to do that, as neither setting the table nor its viewport's margins worked.

@Abderrahmene_Rayene Thanks for your reply.
In the end, I used CustomiDelegate, and the stylesheet of the table usually needs to be added with " "QTableWidget::item { padding:1px; }QTableWidget { gridline-color: #303030; }"

class CustomDelegate : public QStyledItemDelegate
{
public:
    CustomDelegate(QObject* parent = nullptr) : QStyledItemDelegate(parent) {}
    void paint(QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const override
    {
        painter->setPen(QColor(0x303030));
        if (index.row() == 0)
            painter->drawLine(option.rect.topLeft(), option.rect.topRight());
        if (index.column() == 0)
            painter->drawLine(option.rect.topLeft(), option.rect.bottomLeft());
        QStyledItemDelegate::paint(painter, option, index);
    }
};
