我正在开发一个与数据库集成的网站。在其中一个页面中，我提供了许多表格，其中包含不同的信息。这些表具有或者应该具有诸如order by，seach，每页行数等功能，并且所有功能都确实有效。

现在假设我使用完全相同的代码创建两个表。发生的事情是，第一个具有我之前列举的那些功能，但第二个没有。该表将显示正确的信息，但没有功能。我不明白为什么，因为代码完全一样。这是我正在使用的代码：

<div class="content-box-large">
            <div class="panel-heading">
                <div class="panel-title"><b>Eventos</b></div>
            </div>
            <div class="panel-body">
                <table cellpadding="0" cellspacing="0" border="0" class="table table-striped table-bordered" id="example">
                    <thead>
                        <tr>
                            <th>Nome</th>

                            <th>Local</th>
                            <th>Data de Início</th>
                            <th>Data de Fim</th>
                        </tr>

                        $resultado_Eventos          = mysqli_query($ligacao,$SQL_Eventos);

                        if($resultado_Eventos)
                        {
                            while($tuplo = mysqli_fetch_array($resultado_Eventos))

修改

所以我发现问题是id。如果我有1个或2个或3个表没关系，只有我有我的id =“example”，功能才有效，但由于我不能有两个具有相同id的表，我怎么能克服这个？
