荐 pyqt5 tableWidget入门，和treewidget联动功能

1.成品

最近在做项目的过程中需要用到QTreeWidget和QTableWidget联动，上一篇文章介绍了 QTreeWidget的基本用法，这里介绍一下QTableWidget的基本用法，及我在项目中的使用。先看看最终成品。

要实现以上图片中的功能，需要在上一篇文中加上QTableWidget。所以先介绍下QTableWidget。

2. QTableWidget类

QTableWidget类中的常用方法如下表：

方 法	描 述
setRowCount(int row)	设置QTableWidget表格控件行数
setColumnCount(int col)	设置QTableWidget表格控件列数
setHorizontalHeaderLabels()	设置QTableWidget表格控件的水平标签
setVeriticalHeaderLabels()	设置QTableWidget表格控件的垂直标签
setItem(int, int, QTableWidgetItem)	在QTableWidget表格控件的每个选项的单元空间里添加控件
horizontalHeader	获取QTableWidget表格控件的表格头，以便执行隐藏
rowCount()	获取QTableWidget表格控件的行数
columnCount()	获取QTableWidget表格控件的列数
setEditTriggers(EditTriggers triggers)	设置表格是否可编辑。设置编辑规则的枚举值
setSelectionBehavior	设置表格的选择行为
setTextAlignment	设置表格内文字的对齐方式
setSpan(int row, int column, int rowSpanCount, int columnSpanCount)	合并单元格，要改变单元格的第row行第column列，要合并rowSpanCount行数和columnSpanCount列数。 ·row： 要改变的单元格行数 ·column要改变的单元格列数 ·rowSpanCount：需要合并的行数 ·columnSpanCount：需要合并的列数
setShowGrid()	在默认情况下，表格的显示是有网格线的。 · True：显示网格线 · False：不显示网格线
setColumnWidth(int column, int width)	设置单元格的宽度
setRowHeight(int row, int height)	设置单元格的高度

编辑规则中的枚举类型：

选 项	值	描述
QAbstractItemView:NoEditTriggers0No	0	不能对表格内容进行修改
QAbstractItemView:CurrentChanged1Editing	1	任何时候都能对单元格进行修改
QAbstractItemView:DoubleClicked2Editing	2	双击单元格
QAbstractItemView:SelectedClicked4Editing	4	单击已选中的内容
QAbstractItemView:EditKeyPressed8Editing	8	当修改键被按下时修改单元格
QAbstractItemView:AnyKeyPressed16Editing	16	按任意键修改单元格
QAbstractItemView:AllEditTriggers31Editing	31	包括以上所有条件

表格的选择行为的枚举值类型：

选 项	值	描述
QAbstractItemView.SelectItems0Selecting	0	选中单个单元格
QAbstractItemView.SelectRows1Selecting	1	选中一行
QAbstractItemView.SelectColumns2Selecting	2	选中一列

单元格文本的水平对齐方式：

选 项	描 述
Qt.AlignLeft	将单元格的内容沿单元格的左边缘对齐
Qt.AlignRight	将单元格的内容沿单元格的右边缘对齐
Qt.AlignHCenter	在可用空间中，居中显示在水平向上
Qt.AlignJustify	将文本在可用空间中对齐，默认是从左到右

单元格文本的垂直对齐方式：

选 项	描 述
Qt.AlignTop	与顶部对齐
Qt.AlignBottom	与底部对齐
Qt.AlignVCenter	在可用空间中，居中显示在垂直方向上
Qt.AlignBaseline	与基线对齐

如果要设置水平和垂直对齐方式，比如在表格空间内上下、左右居中对齐，那么只要使用Qt.AlignHCenter和Qt.AlignVCenter即可。

3. 代码实现

在上一篇文章的基础上加上QTableWidget类

class TableWidgetClass(QWidget):

    def __init__(self, tablewidget):
        # noinspection PyArgumentList
        super(TableWidgetClass, self).__init__()
        self.tableWidget = None
        self.initui(tablewidget)
        self.twrowcnt = 0

    def initui(self, tablewidget):
        # layout = QHBoxLayout()

        self.tableWidget = tablewidget
        self.tableWidget.setColumnCount(4)
        self.tableWidget.setRowCount(0)

        # 设置头label
        self.tableWidget.setHorizontalHeaderLabels(['测试用例', '执行时间', '结果', '备注'])

        # 设置列宽度
        self.tableWidget.setColumnWidth(0, 200)
        self.tableWidget.setColumnWidth(1, 130)
        self.tableWidget.setColumnWidth(2, 100)
        self.tableWidget.setColumnWidth(3, 400)

        # 优化3 将表格变为禁止编辑
        self.tableWidget.setEditTriggers(QAbstractItemView.NoEditTriggers)
        # 优化 4 设置表格整行选中
        self.tableWidget.setSelectionBehavior(QAbstractItemView.SelectRows)

    def table_append(self, str_info):
        if str_info == 'CCO测试项' or str_info == 'STA测试项' or str_info == '协议一致性' \
                or str_info == '通信性能测试' or str_info == 'CCO性能测试项' or str_info == 'STA性能测试项':
            return
        item = self.tableWidget.findItems(str_info, Qt.MatchExactly)
        if not item:
            row = self.tableWidget.rowCount()
            self.tableWidget.insertRow(row)
            newitem = QTableWidgetItem(str_info)
            self.tableWidget.setItem(row, 0, newitem)

    def table_remove(self, str_info):
        item = self.tableWidget.findItems(str_info, Qt.MatchExactly)
        if item:
            row = item[0].row()
            self.tableWidget.removeRow(row)

全部的实现代码如下，同样分为2个文件：
