New-HTMLTable grouping hide column

[huntantr]

I have grouping working for the table, but is it possible to hide the column being used for the grouping.

I would like to see something like:

groupproperty
columnproperty1|columnproperty2|columnproperty3

currently I get.
groupproperty
groupproperty|columnproperty1|columnproperty2|columnproperty3
