Copy selected rows of a table to a model

[panoss]

I want to make a new model containing only the selected rows of this table.
Appending the selected rows to the empty model named "selected_rows_model" (QSqlTableModel).

QItemSelectionModel *selectionModel = ui.devices_finder_tbl->selectionModel();
    if(selectionModel->hasSelection() ){       
            //QModelIndexList list = selectionModel->selectedRows();
             QModelIndexList list = ui.devices_finder_tbl->selectedIndexes();
            for(int i = 0; i < list.size(); i++)
            {
                QModelIndex index = list.at(i);
                selected_rows_model->insertRow(selected_rows_model->rowCount(), index);
            }
	}

QItemSelectionModel *selectionModel = ui.devices_finder_tbl->selectionModel();
    if(selectionModel->hasSelection() ){       
            //QModelIndexList list = selectionModel->selectedRows();
             QModelIndexList list = ui.devices_finder_tbl->selectedIndexes();
            for(int i = 0; i < list.size(); i++)
            {
                QModelIndex index = list.at(i);
                selected_rows_model->insertRow(selected_rows_model->rowCount(), index);
            }
	}

To copy to clipboard, switch view to plain text mode 

But it's not working, this row:

selected_rows_model->insertRow(selected_rows_model->rowCount(), index);

selected_rows_model->insertRow(selected_rows_model->rowCount(), index);

To copy to clipboard, switch view to plain text mode 

is wrong.
Ho can I fix it?
