在pyqt4中并排对齐qtexttable和qimage

Question

我目前正在使用pyqt构建GUI，有人知道我如何在qtextdocument中将qtexttable和qimage彼此对齐。它们目前堆叠在一起，但是我希望它们可以并排插入。请在下面找到我的代码。表和图像都嵌入在qtext文档中。

            cursor = self.textEdit.textCursor()
            cursor.insertTable(len(col_tablerender), 2)

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

我希望这样的东西
