Json Datatables服务器端代码

我的表代码是

<table class="table responsive-table" id="sorting-advanced">
                <thead>
                    <tr>
                        <th scope="col">Estado</th>      
                        <th scope="col" width="5%" class="align-center hide-on-mobile">Registo</th>
                        <th scope="col" width="5%">Expiração</th>
                        <th scope="col" width="5%" class="align-center hide-on-mobile">Inserção</th>
                        <th scope="col" width="10%">Dominio</th>
                        <th scope="col" width="10%" class="align-center hide-on-mobile">Titular</th>
                        <th scope="col" width="15%" class="align-center hide-on-mobile">Morada Tit.</th>
                        <th scope="col" width="10%">Email Tit.</th>
                        <th scope="col" width="15%" class="align-center hide-on-mobile">Localidade Tit.</th>
                        <th scope="col" width="15%" class="align-center hide-on-mobile">Cód. Postal</th>
                        <th scope="col" class="align-center hide-on-mobile">Nome Ent.</th>
                        <th scope="col" class="align-center hide-on-mobile">Email Ent.</th>
                        <th scope="col" class="align-center hide-on-mobile">Nome Tec.</th>
                        <th scope="col" class="align-center hide-on-mobile">Email Tec.</th>
                        <th scope="col" width="10px" >IP</th>
                        <?php if ($_SESSION['update'] == '1'){echo '<th scope="col" width=20px>Black</th>';} ?>

                    </tr>
                </thead>
                <tbody>

                </tbody>

                <tfoot>

                </tfoot>
            </table>

但是当我装填的时候，桌子什么都没做。。。 中间只有一个白色的方块，没有任何负载… 如果我将sAjaxsource更改为allraedy工作的文件，它将显示结果，但输出JSON格式相同

有人知道为什么会这样吗（

我能想到的唯一一件事是，您是否从文档中发回了表创建的相同的sEcho

string sEcho从客户端发送的sEcho的未更改副本。 此参数将随每次绘图而更改（基本上是绘图 因此，实现这一点非常重要 出于安全原因，强烈建议您“强制”此 参数设置为整数，以防止跨站点脚本（XSS） 攻击

如果您总是使用相同的json进行响应，那么应该省略sEcho（并且知道省略它的危险性）
