The same way as however you say you currently do it? Copy whatever data you want from one QTableWidget to another.

thanks for your reply , but when you use this solution you must reload the file .
What i want is loading the file for only one time then display some lines on another tablewidget .
I hopeb that my question is clear :)

Then load it just once and put (= copy) the data in both tableWidgets. There should be no problem at all.

Use QSortFilterProxyModel to filter out the rows you don't want in the second view and call QTableView::setModel passing the proxy

in the header

private:
QSortFilterProxyModel *m_filterProxy;
QTableView* m_secondTable;

in the source

m_filterProxy = new QSortFilterProxyModel(this);
m_filterProxy->setSourceModel(tableWidget.model());
m_filterProxy->setFilterRegularExpression(QStringLiteral("^[Aa].*")); // only show items starting with A
m_secondTable = new QTableView(this);
m_secondTable->setModel(m_filterProxy);
// m_secondTable->show();
