Thanks!  Totally logical now that I see it.  But not apparent from any docs 
I've ever read.  Before asking I Googled and found other people with the same 
problem, but not the answer.  Thanks again.

 I have:

 and am getting the error message:
 
 Could not resolve mx:columns to a component implementation
 
 MyBetterDataGrid extends DataGrid.  Why isn't the compiler letting me declare 
 the columns?  Is there a way to do this?  Thanks.

You're making a new DataGrid that will reuse the existing DataGridColumn. 
You're new DataGrid will have it's own column property.
So you need to prefix MyBetterDataGrid and 'columns' with you're namespace, 
but keep the DataGridColumn's themselves in the default 'mx' namespace.
