title: Column layout - how to set textfield witdth
body: <p>I have a formpanel which contains textfield items. <a href="https://fiddle.sencha.com/#view/editor&amp;fiddle/1mo6" rel="nofollow noreferrer">Here is a fiddle demonstrating my current screen</a></p>
  
  <p>Is there anyway to make the width of the textfield take up less than the entire width of the column? Basically, I want the columns stay at the sizes they are (2 columns at 50% each), but I do not want the textfield taking up that entire space of the column. </p>
  
  <p>Can this be achieved using a column layout like I have now?</p>
