Hello, i'm playing around with the theme feature and i would like to apply a border around the freeform dw fields

        "dwo-column":
        {
            "drawing":true,
            "border":1,
            "border-color":"#7f7f7f",
            "background-color":"#FFFFFF",
            "text-font":{"color":"#000000"},

everything working fine but i would like, if possible, to disable this border for the tabular datawindows type that i'm usually using for printing reports and those borders are not always very cool.

Is there a way to disable the drawing parameter for the tabular datawindow type? I've noticed i can disable it for grid style, but not for tabular.
For now the only workaround i've found is to enable the print preview of the datawindow which seems to disable the fields border even on the screen. Too bad it applies the margins too.
Is there any other way to accomplish this?

tia,

simone
