Replace all nan values in a UITable with 0

I am trying to replace all nan values in a uitable in MATLAB App designer with zeros. I tried using

app.UITable(isnan(app.UITable)) = 0; 

but it doesn't change the nan values to zero

I used

app.UITable.Data = fillmissing(app.UITable.Data, 'constant', 0);

and all nan values were replaced by zero
