i think you need to say like this...
your header text like this... "Column 1 is Used For.." then it will be displayed like this..
"Column 1 is
Used For.."
m i right..?
and you need to display like "Column 1 is Used For..."
so you need to apply css class for header with the property like this...
.HeaderText
{
white-space:nowrap;
}
