具有服务器端处理问题的数据表

>我有一个脚本来编码json字符串，以便以jquery数据表格式显示数据。

但是，该页面未显示任何内容！如果我使用 jquery .post 进行简单的响应，则会显示数据，但该表会失去其功能。

这是我到目前为止所做的

JSON 编码脚本

$user = new Users();
$rcs_user = $user->get_all_users();
$response = '';
$arrResp = array();
$arrItems = array();
foreach ($rcs_user as $info)
{

    $arrItems = array(utf8_encode($info->nome),$info->email,$info->permissao,$info->activo,'<span class="tip" >
                    <a  title="Edit" ><img src="images/icon/icon_edit.png" ></a>
                    </span> 
                    <span class="tip" >
                    <a id="1" class="Delete"  name="Band ring" title="Delete"  >
                    <img src="images/icon/icon_delete.png" >
                    </a></span>');
    array_push($arrResp, $arrItems);
}
$array = array("aaData"=>$arrResp);
echo json_encode($array);

脚本输出的 JSON 字符串（使用 JSONLint 验证）

{
"aaData": [
    [
        "admin",
        "a@a.pt",
        "1",
        "1",
        "'r'n  </a>'r'n </span> 'r'n 'r'n 'r'n  'r'n </a></span>"
    ],
    [
        "admin2",
        "a@a.pt",
        "1",
        "1",
        "'r'n  </a>'r'n </span> 'r'n 'r'n 'r'n  'r'n </a></span>"
    ],
    [
        "António",
        "a@a.com",
        "10",
        "0",
        "'r'n  </a>'r'n </span> 'r'n 'r'n 'r'n  'r'n </a></span>"
    ],
    [
        "João Dias",
        "a@a.com",
        "10",
        "0",
        "'r'n  </a>'r'n </span> 'r'n 'r'n 'r'n  'r'n </a></span>"
    ],
    [
        "Zé Manel",
        "zemanel@ze.com",
        "10",
        "1",
        "'r'n  </a>'r'n </span> 'r'n 'r'n 'r'n  'r'n </a></span>"
    ]
]
}

最后是jQuery

 $(document).ready(function() {
            $('#data_table3').dataTable( {
                    "bProcessing": true,
                    "bServerSide": true,
                    "sAjaxSource": 'modules/user/showusers.php'
                } );
            } );

每次重新加载页面时，我都会收到此警报消息

Datatables Warining (tableid = data_table3): Cannot reinitialize table data. To retrieve the Data Objects for this table pass no arguments or see the docs for bRetrieve or bDestroy.

如果我能做到这一点，那将是一个巨大的帮助！
