Webgrid Format of datetime and setting style

I'm struggline with syntax gremlins with the WebGrid. In my normal razor markup i format a date inside my foreach like so

<td>
        @String.Format("{0:MM/dd/yy hh:mm:ss}", item.complianceedatetime)
    </td>

and I set my column width like so

<th width="150px">
        Download Date/Time
    </th>

How would I do this with the Grid.Column syntax

grid.Column("complianceedatetime", "Download Date/Time", ?, ?)
