title: array_name.className gives "className is null or not an object" in IE
body: <p>I am using jQuery Datatables plugin for displaying data.
  This works perfectly in Mozilla and Chrome but in IE, it produces 
  "className is null or not an object" error at the following line
  of code in jQuery.Datatables.js</p>
  
  <p><strong>Code:</strong>
  if ( nTds[i].className.indexOf(sClass+"1") != -1 )
  {
      for ( j=0, jLen=(nTds.length/iColumns) ; j
  
  <p>I am not sure if the problem pertains to "indexOf" or "className"
  as IE does not support indexOf</p>
  
  <p>Any help on this issue would be appreciated</p>
