I found a solution. Just remove dataType and format.
{ headerText: 'Id', key: 'ID', width:'50px' }
Formatter approach does not work either. The val variable is a number type so there is no comma to strip even if you toString the value.

Hi Troy,
Your suggested solution does not works. Here is the link to the image to show the result. sdrv.ms/18nfL7E
