添加选择框
在代码中设置tablewidget的样式表

    setStyleSheet(
                "QTableWidget{ color:black; \
                                 background-color:rgb(224,224,224);\
                                 selection-color:rgb(0, 0, 0); \
                                 selection-background-color:rgb(	100,149,237);\
                                 border:0px;\
                                 font: 8pt 'Microsoft YaHei' ;}"
                "QHeaderView::section:horizontal{ 	/*设置标题(水平的)*/\
                                border: 1px solid rgb(255, 255, 255); 	/*白色间隔*/\
                                border - bottom: 0px;/*下边框不需要颜色*/\
                                color: rgb(2, 65, 132);\
                                background: rgb(	100,149,237);\
                                padding - left: 2px;\
                                min - width:60px;}");

设置表格，添加选择框


     //设置列数
     ui->tableWidget->setColumnCount(3);
     //设置行数
     ui->tableWidget->setRowCount(3);
     //设置整行选中
     ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);
     //表头标题
     QStringList headerText;
     headerText<<"序  号"<<"名  称"<<"选  择";
     ui->tableWidget->setHorizontalHeaderLabels(headerText);
     //设置列宽
     ui->tableWidget->setColumnWidth(0,ui->tableWidget->width()/3);
     ui->tableWidget->setColumnWidth(1,ui->tableWidget->width()/3);
     ui->tableWidget->setColumnWidth(2,ui->tableWidget->width()/3);
     //去除垂直表头
     ui->tableWidget->verticalHeader()->setVisible(false);
     //去除选中虚线框
     ui->tableWidget->setFocusPolicy(Qt::NoFocus);
     //禁止编辑
     ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);
     //添加项
     for (int i=0; i<3; i++) {
         ui->tableWidget->setItem(i,0,new QTableWidgetItem(QString::number(i+1)));
         ui->tableWidget->setItem(i,1,new QTableWidgetItem("aaa"));
         //添加选择框
         QTableWidgetItem *check = new QTableWidgetItem();
         check->setCheckState(Qt::Unchecked);
         ui->tableWidget->setItem(i, 2, check);
         //元素居中
         ui->tableWidget->item(i,0)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
         ui->tableWidget->item(i,1)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
         ui->tableWidget->item(i,2)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);

     }

cellClicked事件响应，当点击表格项，对复选框进行选中和取消选择

void MainWindow::on_tableWidget_cellClicked(int row, int column)
{
    //判断选择状态
    if(ui->tableWidget->item(row,2)->checkState() == Qt::Checked){
        //设置选择状态
        ui->tableWidget->item(row,2)->setCheckState(Qt::Unchecked);
    }else{
        ui->tableWidget->item(row,2)->setCheckState(Qt::Checked);
    }

}

qt设置tablewidget颜色、添加选择框、添加按钮和进度条
添加进度条和按钮
设置表格


    //设置列数
    ui->tableWidget->setColumnCount(3);
    //设置行数
    ui->tableWidget->setRowCount(2);
    //设置整行选中
    ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);
    //表头标题
    QStringList headerText;
    headerText<<"序  号"<<"按  钮"<<"进度条";
    ui->tableWidget->setHorizontalHeaderLabels(headerText);
    //设置列宽
    ui->tableWidget->setColumnWidth(0,ui->tableWidget->width()/3);
    ui->tableWidget->setColumnWidth(1,ui->tableWidget->width()/3);
    ui->tableWidget->setColumnWidth(2,ui->tableWidget->width()/3);
    //去除水平表头
    ui->tableWidget->verticalHeader()->setVisible(false);
    //去除选中虚线框
    ui->tableWidget->setFocusPolicy(Qt::NoFocus);
    //禁止编辑
    ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);

    //添加控件
    QPushButton *button0 = new QPushButton("按钮0");
    QPushButton *button1 = new QPushButton("按钮1");
    m_pProgress0 = new QProgressBar();
    m_pProgress1 = new QProgressBar();
    ui->tableWidget->setCellWidget(0,1,button0);
    ui->tableWidget->setCellWidget(0,2,m_pProgress0);
    ui->tableWidget->setCellWidget(1,1,button1);
    ui->tableWidget->setCellWidget(1,2,m_pProgress1);
    //添加项
    for (int i=0; i<2; i++) {
        ui->tableWidget->setItem(i,0,new QTableWidgetItem(QString::number(i+1)));
        //元素居中
        ui->tableWidget->item(i,0)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
    }

建立按钮和处理函数的信号槽连接，让按钮点击，进度条移动

    //建立信号槽连接
    connect(button0,SIGNAL(clicked()),this,SLOT(progress0()));
    connect(button1,SIGNAL(clicked()),this,SLOT(progress1()));

槽函数和进度条控件

private slots:
    void progress0();
    void progress1();
private:
    Ui::MainWindow *ui;
    QProgressBar *m_pProgress0;
    QProgressBar *m_pProgress1;


void MainWindow::progress0(){
    m_pProgress0->setValue(m_pProgress0->value()+10);
}
void MainWindow::progress1(){

    m_pProgress1->setValue(m_pProgress1->value()+10);
}
