I don t want add an external png, how I can do it?

    ui->tableWidget->setItem(j, 0, new ??? );

You generate QImage with setColor tranform with QPixmap::fromImage for instance.

auto model = ui->tableWidget->model();
QPixmap greenSquare(20,20);
greenSquare.fill(Qt::green);
for(int i=0, maxRow = model ->rowCount();i<maxRow ;++i)
model->setData(model->index(i,0),greenSquare,Qt::DecorationRole);
