QTableView样式

控件的成员函数styleSheet()可以获取控件的风格样式
ui->tableView_contact_1->setWindowTitle("Contact List1");
ui->tableView_contact_1->setShowGrid(false);//隐藏网格
//选择整行
ui->tableView_contact_1->setSelectionBehavior(QAbstractItemView::SelectRows);
//设置表格的单元为只读属性，即不能编辑
ui->tableView_contact_1->setEditTriggers(QAbstractItemView::NoEditTriggers);

//隐藏左边的列和上面的行
ui->tableView_contact_1->verticalHeader()->hide();

ui->tableView_contact_1->verticalScrollBar()->setStyleSheet("QScrollBar:vertical{width:10px;background:rgba(255,255,255,60);margin:0px,0px,0px,0px;padding-top:5px;padding-bottom:5px;}QScrollBar::handle{background:rgb(4,122,217);border: 1px solid #ffffff;}QScrollBar::add-line:vertical{background:rgba(255,255,255,60);height:5px;subcontrol-position: bottom;}QScrollBar::sub-line:vertical{background: rgb(255,255,255,60);height: 5px;subcontrol-position: top;}QScrollBar::add-page:vertical,QScrollBar::sub-page:vertical{background:qlineargradient(spread:reflect, x1:0, y1:0, x2:1, y2:0, stop:0 rgba(255,255,255,60),stop:1 rgba(255,255,255,60));border:1px,solid,rgba(255,255,255,60);}");

ui->tableView_contact_1->horizontalHeader()->setDefaultAlignment(Qt::AlignLeft);
//列宽度自适应
