title: Fixing number of columns in javafx TableView
body: <p>I have 4 columns in my dynamically generated tableView in javafx. But in th UI I get an additional column with no text set. I want to ramove it and keep just four columns. How can I do that?
  Also the table is not responsive. I have set it to grow it on all the sides but only that extra column grows. All the other columns attain the width as given to them initially in the Scene Builder. I want the table to be responsive. How can I achieve that?</p>
