title: JqGrid Specifying the Column Label using colNames vs using label property from colNames
body: <p>I have been using jqGrid for a while And I am just wondering what the difference is between using colNames to specify the Label as shown </p>
  
  <pre class="lang-js prettyprint-override"><code>colNames:['Actions','Inv No'],
  colModel [
      {name:'act',index:'act',width:55,align:'center'},
      {name:'inv',width:100,align:'left'}
  ]
  </code></pre>
  
  <p>OR using the Label property of colModel as shown below</p>
  
  <pre class="lang-js prettyprint-override"><code>colModel [
      {label:'Actions', name:'act',index:'act',width:55,align:'center'},
      {label:'Inv No', name:'inv',width:100,align:'left'}
  ]
  </code></pre>
