hi all, is there a way to prevent a grid from showing a default empty row

hi all,
is there a way to prevent a grid from showing a default empty row ?
i did some test.
this will occur when the grid includes a true/false column or dropdown column(these fields are all not required).

however if you set null as default value to true/false field, sometimes the default empty row disappears.
accturally i have two models. grids in the two models both only have text and true/false columns. but one grid does not show default empty row, and the other still shows the empty row. the value of the true/false column is false.

i hope i make the question clear.

thanks in advance.

fyi, i'm using appian6.71....
