QStringList to QList<QStandardItem *>

I have a list in QStringList with some items like this:

("name0", "name1", "name2",...)

that I need to pass to a QTableView using: 

appendRow(const QList<QStandardItem *> &)

so how can I get QList from QStringList to add items to my table?

With QTableView you have to use a model. Usually this is done by subclassing QAbstractTableModel. More on the different Qt models here: https://doc.qt.io/qt-5/model-view-programming.html

If you just want to display a simple table i suggest using QTableWidget. The API works like this:

QStringList list = QStringList() << "name0" << "name1" << "name2";

ui->tableWidget->setColumnCount(list.size());
ui->tableWidget->insertRow(ui->tableWidget->rowCount());

for (int i = 0; i < list.size(); ++i)
    ui->tableWidget->setItem(ui->tableWidget->rowCount() - 1, i,
            new QTableWidgetItem(list.at(i)));

for adding data in columns and adding labels i would suggest this code:

ui->tableWidget->setHorizontalHeaderLabels({"List1", "List2"});

QStringList list1 = QStringList() << "name0" << "name1" << "name2";
QStringList list2 = QStringList() << "surname0" << "surname1" << "surname2" << "surname3";

addColumn(list1);
addColumn(list2);

function for adding columns:

void MainWindow::addColumn(const QStringList &list)
{
    // resize rowcount as needed. qMax needs #include <QtMath>
    ui->tableWidget->setRowCount(qMax(list.size(), ui->tableWidget->rowCount()));

    ui->tableWidget->insertColumn(ui->tableWidget->columnCount());

    for (int i = 0; i < list.size(); ++i)
        ui->tableWidget->setItem(i, ui->tableWidget->columnCount() - 1, new QTableWidgetItem(list.at(i)));
}

This works:

QStringListModel *model = new QStringListModel({"a","b","c"});
QListView view;
view.setModel(model);

You don't need to use a QStandardItemModel for this case and it can just be a QListView.
