$('#mgtable').dataTable({
           sPaginationType: "full_numbers", "bJQueryUI" : true,"sDom": '<"H"lfr>t<"F"ip>',
           "aoColumnDefs": [
               { "aTargets":[ "mgName" ], "mData": "Name",sClass:"Name", "bAutoWidth": false },
               { "aTargets":[ "gcb" ], "mData": "CreatedBy.Name", sClass:"CBName", "bAutoWidth": false },
               { "aTargets":[ "desc" ], "mData": "Client_Group_Description__c", sClass:"CGDesc", "bAutoWidth": true }
           ],
          "fnInitComplete": function(oSettings) { 
                  MasterDetailListController1.refreshMasterGroupList(function(result, event){
                     if(event.type == 'exception') {
                        alert(event.message);         
                     } else {   
                       $('#mgtable').dataTable().fnAddData(result);         
                     }
                   });
           },
           "fnCreatedRow": function( nRow, aData, iDataIndex ) {
                                 $('td:eq(0)', nRow).html( '<input type="checkbox" name="checkbox" class="checkbox" value="'+ aData.Id+'">');

                         } 

    }); 

    <table id="mgtable" class="display">
        <thead>
            <th><input type="checkbox" id="selectall"/></th>
            <th class="mgName">Master Group Name</th>
            <th class="gcb">Group Created By</th>
            <th class="desc">Description</th>
        </thead>
        <tbody></tbody>
    </table>

Apex Controller:

public with sharing class DataTableController { 
  @RemoteAction
  public static list<Client_Group__c> refreshMasterGroupList() {
    return [select id,Name,CreatedBy.Name,Client_Group_Description__c from Client__c order by Name];
  }
}
