01 QTableWidget *tableWidget = new QTableWidget;
02 QTableWidgetItem *firstColumn = new QTableWidgetItem(tr("test"));
03 firstColumn->setCheckState(Qt::Checked);//加入复选框
04 connect(tableWidget, SIGNAL(cellChanged(int,int)), this, SLOT(changeTest(int, int)));
05 void changeTest(int row, int col)
06 {
07 if(tableWidget ->item(row, col)->checkState() == Qt::Checked)
08 ...
09 else
