有一段英文文本（这样我们不用考虑中文文本导致的对齐问题），该文本有多行，每行前后可能会有空格，每行前面的空格要保留，而每行最后的空格应该去除。请在这段英文文本上面加上装饰栏，如下所示。 text = r''' The King and Queen of Hearts were seated on their throne when they arrived,with a great crowd assembled about them--all sorts of little birds and beasts, as well as the whole pack of cards: the Knave was standing before them, in chains, with a soldier on each side to guard him; and near the King was the White Rabbit, with a trumpet in one hand, and a scroll of parchment in the other. In the very middle of the court was a table, with a large dish of tartsupon it: they looked so good, that it made Alice quite hungry to look at them-- `I wish they'd get the trial done,' she thought, `and hand round the refreshments!' But there seemed to be no chance of this, so she began looking at everything about her, to pass away the time.'''
