add empty row in row grouping function

avb

Hi ,
I use the datatable "row grouping" function. Its works great !
I would like to add an "empty" row after each row group to have a more readable table. Is it possible ?

On the following code , can i add an empty row with a new <tr> ?

if ( last !== group ) {
$(rows).eq( i ).before(
'<tr class="group"><td colspan="5">'+group+'</td></tr>'
);

Thanks for your help!

okey, Its works with a new <tr> and a css class

if ( last !== group ) {
$(rows).eq( i ).before(
'<tr><td class= "espace" colspan="5"></td></tr>'
'<tr class="group"><td colspan="5">'+group+'</td></tr>'
);
