单个表格 cell 内绑定若干个 button

单独的函数用于往 table 每一行指定 Action 列的单个 cell 中写入若干个 button

def fn_add_button_for_row(list_info, row_index, curr_column_name):
    dict_button = dict()
    widget = QWidget()
    hLayout = QHBoxLayout()
    # add several buttons
    for index, value in enumerate(list_info[row_index][curr_column_name]):
        btn = QtWidgets.QPushButton(value)
        btn.setStyleSheet(''' text-align : center;
                      background-color : LightCoral;
                      height : 30px;
                      border-style: outset;
                      font : 13px; ''')
        dict_button['btn' + str(index + 1)] = btn
        hLayout.addWidget(btn)
    hLayout.setContentsMargins(5,2,5,2)
    widget.setLayout(hLayout)
    return dict_button, widget

显示整个 table 时须调用上述函数：

    for row_index in range(row_num):
        dict_button = dict()
        item = QtWidgets.QTableWidgetItem()
        certain_table.setVerticalHeaderItem(row_index, item)
        certain_table.verticalHeaderItem(row_index).setText(_translate("MainWindow", str(row_index + 1))) # set table vertical header index
        for column_index in range(column_num):
            item = QtWidgets.QTableWidgetItem()
            item.setFlags(QtCore.Qt.ItemIsEnabled)
            certain_table.setItem(row_index, column_index, item)
            curr_column_name = list_column_name[column_index]
            value = list_info[row_index][curr_column_name]
            if curr_column_name != "Action": # get the letters except the last two digits
                certain_table.item(row_index, column_index).setText(_translate("Dialog", str(value)))
            else:
                # draw buttons for actions
                dict_button, widget = fn_add_button_for_row(list_info, row_index, curr_column_name)
                certain_table.setCellWidget(row_index, column_index, widget)
