Space in datagrid column Name

Hello all,

I am populating a datagrid with a dataprovider array.

I added the column Names like “Phase Vol.” , “Figure No.” etc. by doing

Dg.addColumn (“Phase Vol.”)

Dg.addColumn (“Figure No.”);

now i want to asign a data in it by doing something like this

var item_obj:Object = { Phase Vol :“01”, Figure No :30};
Dg .addItem (item_obj);

But the problem here is it does not take the space in property Name… How do I keep my column Names value different?

Regards,
Mayur
