推荐答案

Deedle具有的 RealignRows 扩展方法，但事实证明，我们没有 RealignColumns 。这是一个疏忽，如果你发送一个公关Deedle添加此，这将是真棒！

Deedle has RealignRows extension method, but it turns out that we don't have RealignColumns. This is an omission and if you send a PR to Deedle adding this, that would be awesome!

它可以通过查看该系列列，重新调整列实施并把该回的数据帧。在C＃中，这看起来如下：

It can be implemented by looking at the series of columns, realigning the columns and turning that back into a data frame. In C#, this looks as follows:

Frame.FromColumns(df.Columns.Realign(new[] { "key 1", "key 2" }));
