一、效果展示

二、主要代码

void MainWindow::init()
{

    QStringList labels;
    labels<<QString::fromLocal8Bit("学号")<<QString::fromLocal8Bit("姓名")
         <<QString::fromLocal8Bit("性别");

    //设置行与列
    ui->tableWidget->setColumnCount(3);
    ui->tableWidget->setRowCount(1);

    //创建表头
    ui->tableWidget->setHorizontalHeaderLabels(labels);

    //设置表头样式
    ui->tableWidget->horizontalHeader()->setStyleSheet("QHeaderView::section{background:rgb(245,245,245);}");

    //修改单元格选中后的背景色
    ui->tableWidget->setStyleSheet("selection-background-color: rgb(245, 245, 250);");

    //设置纵向表头
    ui->tableWidget->verticalHeader()->setStyleSheet("QHeaderView::section{background:rgb(245,245,245);}");

    //设置为只读模式
    ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);
    addData();
}
void MainWindow::addData()
{
    QTableWidgetItem *item;
    QTableWidgetItem *genderItem;
    ui->tableWidget->setRowCount(10);
    QFont font;

    //设置加粗
    font.setBold(true);
    font.setPixelSize(24);


    for(int i = 0;i<10;i++)
    {

        item = new QTableWidgetItem();
        genderItem = new QTableWidgetItem();

        //设置颜色
        item->setTextColor(Qt::red);
        item->setFont(font);

        //设置内容的对齐方式
        item->setTextAlignment(Qt::AlignHCenter);

        item->setText(QString::number(i));

        //设置第一列内容
        ui->tableWidget->setItem(i,0,item);

        if(0 == i % 2)
        {
            //设置第三列内容
            genderItem->setText(QString::fromLocal8Bit("男"));
            genderItem->setTextColor(Qt::red);
