QtableView - how to increment the table size

Question

Hi,

I am using the following code for display the table. But I want to increase the table size.

QStandardItemModel *model=new QStandardItemModel();
    for (int row = 0; row < 40; ++row) {
           for (int column = 0; column < 3; ++column) {
               QStandardItem *item = new QStandardItem(QString("hi"));
               model->setItem(row, column, item);
           }
       }
    searchTable = new QTableView(this);
    searchTable->showGrid();
    searchTable->setModel(model);

Any suggestions?
