tableWidget

基础使用

        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.tableWidget = QtWidgets.QTableWidget(self.centralwidget)
        self.tableWidget.setGeometry(QtCore.QRect(30, 60, 651, 421))
        self.tableWidget.setObjectName("tableWidget")
        # 指定列数
        self.tableWidget.setColumnCount(2)
        # 设置列名
        titles = ['编号', '姓名', '工资', '入职日期', ' 性别']
        self.tableWidget.setHorizontalHeaderLabels(titles)
        # 指定列数
        self.tableWidget.setRowCount(2)
        # 添加列名
        self.tableWidget.setHorizontalHeaderLabels(('第一列', '第二列'))
        # 插入行
        for i in range(10):
            self.tableWidget.insertRow(i)
        # 添加内容
        self.tableWidget.setItem(1, 1, QTableWidgetItem(str(10)))
        # 设置表格的高度和宽度
        self.tableWidget.resize(self.size().width(),self.size().height())
        # 设置列宽的适应方式
        self.tableWidget.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)
        # 隔行换色
        self.tableWidget.setAlternatingRowColors(True)

属性

合并单元格

    # 合并单元格，当前行、列，合并行数、全并列表
    self.tableWidget1.setSpan(0,0,2,1)

隐藏重直表头

self.tableWidget1.verticalHeader().setVisible(False)

隐藏滚动条

    self.tableWidget1.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarPolicy.ScrollBarAlwaysOff)
    self.tableWidget1.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarPolicy.ScrollBarAlwaysOff)

自适应宽度

self.table = QTableWidget(3, 5)  # 3 行 5 列的表格
        self.table.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)  # 自适应宽度

横向滚动条，列宽可调

self.table.horizontalHeader().setStretchLastSection(True)

列过滤器添加搜索栏
