Yes there is a simple way to hide them,
In the initialize event of the cell you want to hide, write this :
$.presence = "hidden"
If you're in a flowed subform, this might screw up your table a little bit because the table won't only see it as invisible, the table will acts as if they were not there, so it might move your columns in a way you don't want.
If you don't want your table to move like this, simply go into the cell you want to hide. Go into Object->Cell tabs and using the Presence option, put it to invisible. If you want a complete row to dissapear, all the cells within this row must be hidden, if there is one left, the row will still appear.
