Question Modify columns on iostats so all figures line up

As you can see when I add the names the Device column is not big enough to hold all the characters. Is there a way to change the column width of Device or is it hard coded

Code:
Device:         rrqm/s   wrqm/s     r/s     w/s    rMB/s    wMB/s avgrq-sz avgqu-sz   await  svctm  %util

Try to pipe the output to column:
Code:
iostat | column -t

That works... or well this does:

Code:
while [ 1 -eq 1 ] ; do iostat -d -m -x -N 5 2 | grep -v Linux| column -t; done
seems column waits for the entire pipe to finish before outputting and since I'm running it continues it never returns anything.

Thanks.
