Question: I am getting a bug when I use a text\_area in my rails app. The box takes line breaks, and makes them indentation. Here is a screen shot, any idea where these indentations are coming from?

Answer: 
Only by iterating over the rows, as [Utaal noted in this answer](https://stackoverflow.com/questions/1080071/get-all-values-of-a-column-from-a-dataset/1080084#1080084).

You might expect that the `DataTable.DefaultView.RowFilter` would support grouping, but it does not (it mainly offers the equivalent functionality of a `Where` clause, with some basic aggregations - though not simple grouping).
As far as I know there's no direct way to get those; but the for-loop is pretty straightforward and obviously won't be more resource-intensive than anything else.
