QtableWidget 控件 简单使用

做数据库的话 QtableWidget 控件 应该用得很多的，做个记录

    //QtableWidget 控件
    //加水平表头
    QStringList list1;
    list1<<"姓名"<<"性别"<<"年龄";
    ui->tableWidget->setColumnCount(list1.size());
    ui->tableWidget->setHorizontalHeaderLabels(list1);
    ui->tableWidget->setRowCount(10); //设行数
    ui->tableWidget->setItem(0,0,new QTableWidgetItem("jinesc"));
    QStringList nameList;
    nameList<<"kiki"<<"jinesc"<<"bbb";
    QList<QString> sexList;
    sexList<<"女"<<"男"<<"未知";
    for (int i=0;i<3;i++) {
        int col=0;
        ui->tableWidget->setItem(i,col++,new QTableWidgetItem(nameList[i]));
        ui->tableWidget->setItem(i,col++,new QTableWidgetItem(sexList.at(i)));
        ui->tableWidget->setItem(i,col++,new QTableWidgetItem(QString::number(i+20)));
    }
    connect(ui->addButton,&QPushButton::clicked,[=](){
        bool isEmpty=ui->tableWidget->findItems("jinesc.cn",Qt::MatchExactly).empty();
        if(isEmpty){
            ui->tableWidget->insertRow(0);
            int col=0;
            ui->tableWidget->setItem(0,col++,new QTableWidgetItem("jinesc.cn"));
            ui->tableWidget->setItem(0,col++,new QTableWidgetItem("网站"));

        }else{
            QMessageBox::warning(this,"警告","已经添加了jinesc.cn");
        }

    });
    connect(ui->delButton,&QPushButton::clicked,[=](){
        bool isEmpty=ui->tableWidget->findItems("jinesc.cn",Qt::MatchExactly).empty();
        if(isEmpty){
            QMessageBox::warning(this,"警告","已经删除了jinesc.cn");
        }else{
            //找到所在行
            int row=ui->tableWidget->findItems("jinesc.cn",Qt::MatchExactly).first()->row();
            ui->tableWidget->removeRow(row);
        }
    });


    ui->tableWidget->editItem(ui->tableWidget->item(0,1));//编辑某个单元格

运行如图
