Right Justify A Column

I have a number column in my grid:

var numf = new AW.Formats.Number;

How would I make this column appear right-justified (aligned on the right)?

Thanks,

.aw-column-1 {text-align:right}

When this was applied, headers were also affected. How can you exclude the headers? I want the headers to be centered.

.aw-grid-row .aw-column-1 {text-align:right}
