How can I hide the row "No group"?

sersang5

I use:
rowGroup: {
dataSrc: group
}

Where the variable "group" contains the names of the columns I want to order.

When I have no columns to group, the DataTable shows in a row in the top that says "No group".
Can i hide that row when the variable "groups" doesn't have any column name?

I use Ayax to call my Datatable js code, and depending of the data i have columns to group by or not. When i have no columns to group the DataTable show a row in the top that says "No group".

Can I hide that row?
