pyqt5 qtextdocument从右到左对齐并导出为pdf？

Question

我正在开发 pyqt5 项目，我需要将 tableview 导出为 pdf 或 docx。

导出为 pdf 可以正常工作，但我需要设置对齐方式右 o 左，我也试过 html table 但我无法对齐从右到左。
当我尝试导出为 docx 时，它有时无法正常工作，我得到最后一行，有时我会得到迭代错误。

感谢@musicamante 只需以相反的顺序循环列

for row in range(table.rows()):
            for column in range(table.columns()- 1, -1, -1):
                index = model.index(row, column)
                cursor.insertText(str(model.data(index)))
                cursor.movePosition(QtGui.QTextCursor.NextCell)
