title: How should last colum occupy remaining space in jqgrid
body: <p>I have my <code>jqgrid</code> with <code>shrinkToFit: false</code> and <code>autowidth: true</code>
  what I want is the columns should take their respective width specified in the column model and it does. But when the column number is less and the width of grid is more, there is hell lot of space left behind after the last column.</p>
  
  <p>I need the last column to resize to occupy the full available space.</p>
  
  <p>How this can be done?</p>
