jquery – Datatables warning(table id =’example’)：无法重新初始化数据表

我正在使用datatables示例，并得到这样的错误时加载页面：
Datatables warning(table id =’example’)：无法重新初始化数据表。
要检索此表的DataTables对象，不传递任何参数或查看bRetrieve和bDestroy的文档。

我试图测试fnRowCallback

我在这里做错了什么？

解决方法

您正在初始化两次数据表，为什么？

// Take this off
/*
$(document).ready(function() {
    $( '#example' ).dataTable();
} );
*/
$(document).ready( function() {
  $( '#example' ).dataTable( {
   "fnRowCallback": function( nRow,nRow).html( '<b>A</b>' );
     }
   }
 } );
 } );
