How do I make an entire row in a table NaN?

I am trying to make all values in specific rows of a table NaN.

My table (T) contains 4 columns (time, x position, y position, pressure). I use the value of the pressure to determine when X and Y are 'on' or 'off'. I then want to set all values in rows where it is 'off' to NaN

% get on and off T data
isOn = find(T.Pressure >0);
isOff = find(T.Pressure==0);

I have tried the following:

T(isOff,:) = NaN;

as well as:

for  i = 1:length(isOff)
    T(i,:) = NaN
end

But both give the error: Right hand side of an assignment into a table must be another table or a cell array.

What is the issue? Is there a way to do this using vectorization without having an extensive loop?

Thank you for your help!

T(isOff,:) = {NaN};%does this work?

Yes! Thank you!

T{isOff,:} = NaN; % use curly braces {}
