Adding extra column for QTableView while having QSqlTableModel

Since you want to add a column, you columnCount() would probably first get the value from the base class and then add 1

int Manifest::columnCount(const QModelIndex &parent)
{
    return QSqlQueryModel::columnCount(parent) + 1;
}

int Manifest::columnCount(const QModelIndex &parent)
{
    return QSqlQueryModel::columnCount(parent) + 1;
}

To copy to clipboard, switch view to plain text mode 

In data() you would then check if index.column() is your column and if not, delegate to base class as-is.
