Get content of a single cell from a DataGrid in Flex 3

I want to select information 开发者_如何学Cin a single cell from my DataGrid in Flex 3.

Specifically, I'm displaying three phone numbers per line and the user needs to be able to select one of those numbers, from any row, but not the whole row.

While similar to this, I am displaying the DataGrid to the user. The answer for that question was to manipulate the dataProvider, how can I know what cell I've selected in order to do that?

Check this.
