title: Trim DataTables column values
body: <p>I want to show only first 100 characters of my DataTables column's cells. Something like that:</p>
  
  <pre><code>var columns = [
  
     {
        //mDataProp: 'Description'
        mDataProp: function() {
            return Description.subString(0, 100);
        },
        sTitle: 'Description'             
     },
     //
     // other columns 
     //
  ];
  </code></pre>
  
  <p>However I don't know how to assign a value returning from a function, to mDataProp. Thanks for your help.</p>
