qtableWidget复杂界面效果和添加、删除处理

通过界面拖拽，创建ui->tableWidget

设置样式表

1.  
   QTableWidget{background-color:white; border:none;}
2.  
   QTableView::item {border-bottom: 1px solid #d6d9dc;}
3.  
   QTableWidget::item:hover{background-color: rgb(151, 226, 226);}
4.  
   QTableWidget::item:selected{background-color:#E6E6FA}
5.  
    
6.  
   QHeaderView::section, QTableCornerButton:section{
7.  
   padding:3px;
8.  
   margin:0px;
9.  
   color:#000000; /*字体颜色*/
10.  
    border:1px solid #b3beb9;
11.  
    border-left-width:0px;
12.  
    border-right-width:1px;
13.  
    border-top-width:0px;
14.  
    border-bottom-width:1px;
15.  
     
16.  
    /*设置表头真正背景色*/
17.  
    background-color: rgb(195, 195, 195);
18.  
    }
19.  
     
20.  
    /*设置表头样式*/
21.  
    QHeaderView {
22.  
    color: rgb(0, 103, 0);
23.  
    font: bold 10pt;
24.  
    background-color: rgb(195, 195, 195);
25.  
    border: 0px solid rgb(220, 220, 220);
26.  
    border-left-color: rgba(255, 255, 255, 0);
27.  
    border-top-color: rgba(255, 255, 255, 0);
28.  
    border-radius:0px;
29.  
    min-height:29px;
30.  
    }

初始化 ui->tableWidget

1.  
   void Managerform::init()
2.  
   {
3.  
   //ItemWaitSendForm *win = new ItemWaitSendForm();
4.  
   //QModelIndex index = ui->tableWidget->model()->index(0,0);
5.  
   //ui->tableWidget->setIndexWidget(index, win);
6.  
    
7.  
   ui->tableWidget->setRowCount(0);
8.  
   ui->tableWidget->setColumnCount(7);
9.  
    
10.  
    QStringList header;
11.  
    header<<QStringLiteral("用户")<<QStringLiteral("收件人")<<QStringLiteral("地址")
12.  
    <<QStringLiteral("产品")<<QStringLiteral("实付")<<QStringLiteral("快递单号")<<QStringLiteral("操作");
13.  
    //设置表头标签
14.  
    ui->tableWidget->setHorizontalHeaderLabels(header);
15.  
     
16.  
     
17.  
    QFontMetrics fmenu(ui->tableWidget->font());
18.  
    int fontwidth = fmenu.width(tr("中"));
19.  
     
20.  
    ui->tableWidget->setFocusPolicy(Qt::NoFocus); //去掉单元格虚线
21.  
    ui->tableWidget->horizontalHeader()->setMinimumSectionSize(3*fontwidth); //设置最小列宽
22.  
    ui->tableWidget->verticalHeader()->setDefaultSectionSize(3.5*fontwidth); //默认行高
23.  
     
24.  
    ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);//将表格设置为整行选择
25.  
    ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers); //表格设置为禁止编辑
26.  
     
27.  
    ui->tableWidget->resizeRowsToContents(); //行高 根据内容自动设置
28.  
    ui->tableWidget->resizeColumnsToContents(); //列宽 根据内容自动设置
29.  
    ui->tableWidget->setShowGrid(false); //不显示网格线
30.  
    ui->tableWidget->setWordWrap(true); //允许换行
31.  
    ui->tableWidget->setColumnWidth(0, 6*fontwidth);
32.  
    ui->tableWidget->setColumnWidth(1, 5*fontwidth);
33.  
    ui->tableWidget->setColumnWidth(4, 5*fontwidth);
34.  
    ui->tableWidget->setColumnWidth(5, 8*fontwidth);
35.  
    ui->tableWidget->setColumnWidth(6, 7*fontwidth);
36.  
     
37.  
    ui->tableWidget->horizontalHeader()->setSectionResizeMode(2, QHeaderView::Stretch);//剩余列宽自动填充第2列
38.  
    ui->tableWidget->horizontalHeader()->setSectionResizeMode(3, QHeaderView::Stretch);//剩余列宽自动填充第3列
39.  
    //ui->tableWidget->horizontalHeader()->setStretchLastSection(true); //表格自动填充满
40.  
     
41.  
     
42.  
    ui->tableWidget->setFrameShape(QFrame::NoFrame); //设置边框
43.  
    ui->tableWidget->verticalHeader()->setVisible(false);//设置垂直头不可见
44.  
    //ui->tableWidget->horizontalHeader()->setVisible(false); //设置水平头不可见
45.  
    //ui->tableWidget->setSpan(0, 0, 1, 7); //合并单元格
46.  
     
47.  
    // 对表头文字的字体、颜色进行设置
48.  
    // 获得水平方向表头的item对象
49.  
    // QTableWidgetItem *columnHeaderItem = ui->tableWidget->horizontalHeaderItem(1);
50.  
    // columnHeaderItem->setFont(QFont("Helvetica")); //设置字体
51.  
    // columnHeaderItem->setBackgroundColor(QColor(0,60,10)); //设置单元格背景颜色
52.  
    // columnHeaderItem->setTextColor(QColor(200,111,30)); //设置文字颜色
53.  
     
54.  
    //设置交替行颜色选项(默认是false)
55.  
    ui->tableWidget->setAlternatingRowColors(true); //否则无法交替显示颜色
56.  
    ui->tableWidget->setPalette(QPalette(Qt::lightGray)); //设置隔行变色的颜色 Qt::gray灰色
57.  
    }

每行添加元素

1.  
   void Managerform::onAddItemToWaitSend(TBOrderInfo data)
2.  
   {
3.  
   int row = ui->tableWidget->rowCount();
4.  
   ui->tableWidget->insertRow(row);
5.  
    
6.  
   QModelIndex index = ui->tableWidget->model()->index(row,0);
7.  
    
8.  
   CheckItemForm *widget = new CheckItemForm(ui->tableWidget);
9.  
   widget->setConnect(this);
10.  
    widget->setText(QStringLiteral("yz多喝水"));
11.  
    ui->tableWidget->setCellWidget(row, 0, widget);
12.  
     
13.  
    QTableWidgetItem* pName = new QTableWidgetItem(QStringLiteral("蔡牛牛"));
14.  
    pName->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
15.  
    //pName->setIcon(QIcon(":/image/wang.png"));
16.  
    ui->tableWidget->setItem(row, 1, pName);
17.  
     
18.  
    QTableWidgetItem* pAddress = new QTableWidgetItem(QStringLiteral("1398****984，广西壮族自治区 梧州市 藤县 和平镇 *****门 ，000000"));
19.  
    pAddress->setTextAlignment( Qt::AlignLeft | Qt::AlignVCenter);
20.  
    ui->tableWidget->setItem(row, 2, pAddress);
21.  
     
22.  
    QTableWidgetItem* pProduct = new QTableWidgetItem(QStringLiteral("5瓶装【洗涤剂】 * 2\n5瓶装【洗涤剂】 * 2\n5瓶装【洗涤剂】 * 2"));
23.  
    pProduct->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
24.  
    ui->tableWidget->setItem(row, 3, pProduct);
25.  
     
26.  
    QTableWidgetItem* pActualFee = new QTableWidgetItem(QStringLiteral("176.00元"));
27.  
    pActualFee->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
28.  
    pActualFee->setBackgroundColor(QColor(0,60,10));//1、单元格设置字体颜色、背景颜色、字体字符
29.  
    pActualFee->setTextColor(QColor(200,111,100)); //1、单元格设置字体颜色、背景颜色、字体字符
30.  
    pActualFee->setFont(QFont("Helvetica")); //1、单元格设置字体颜色、背景颜色、字体字符
31.  
    ui->tableWidget->setItem(row, 4, pActualFee);
32.  
     
33.  
    QTableWidgetItem* pMailNo = new QTableWidgetItem(data.logistic.mailNo);
34.  
    pMailNo->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
35.  
    ui->tableWidget->setItem(row, 5, pMailNo);
36.  
     
37.  
    ItemWaitSendForm *operate = new ItemWaitSendForm();
38.  
    operate->setConnect(this);
39.  
    //operate->setData(data);
40.  
    ui->tableWidget->setCellWidget(row, 6, operate);
41.  
     
42.  
     
43.  
    //对所有单元格设置字体
44.  
    //ui->tableWidget->setFont(QFont("Courier"));
45.  
    ui->tableWidget->setFont(QFont("Helvetica"));
46.  
    }

选中某行，这里处理方法比较特别，值得借鉴

1.  
   void Managerform::onCheckedItem(const bool flag)
2.  
   {
3.  
   //获取当前是哪个object发送的新号，
4.  
   CheckItemForm *senderObj = qobject_cast<CheckItemForm*>(sender());
5.  
   QModelIndex idx = ui->tableWidget->indexAt(QPoint(senderObj->frameGeometry().x(), senderObj->frameGeometry().y()));
6.  
   bool enable = senderObj->isChecked();
7.  
   int row = idx.row();
8.  
    
9.  
   if(enable)
10.  
    qDebug()<<QStringLiteral("第%1行 选中").arg(row 1);
11.  
    else
12.  
    qDebug()<<QStringLiteral("第%1行 取消选中").arg(row 1);
13.  
    }
