Question

所以我在一个大的行集上得到一个控制台错误，我正在用PHP从数据库迭代。我正在用metronic主题初始化它。如你所见，我有我的thead和tbody。

我怀疑问题可能与输出的大小有关，可能需要使用其他方法，任何指导意见

<table id="sample_1" class="table table-striped table-bordered table-hover">
    <thead>
          <tr>
            <th class="table-checkbox">
              <input type="checkbox" class="group-checkable" data-set="#sample_1 .checkboxes"/>
            </th>
            <th>Name</th>
            <th>Source</th>
            <th>Email</th>
            <th>Customer</th>
            <th>Created</th>
            <th>Login</th>
            <th>Active</th>
            <th>Role</th>
            <th>Incentive</th>
            <th>View</th>
            <th>Switch</th>
            <th>Email</th>
          </tr>        
        </thead>
      <tbody>

      <?php
        $users=user::get_all($filter);
        if($users){
          foreach($users as $row){
            $customer=user::get_cutomer_name_by_source_id($row['source_id']);
            ?>
            <tr class='odd gradeX'>
              <td><input type='checkbox' class='checkboxes' value='1'/></td>
              <td><?php echo $row['first_name']." ".$row['last_name']; ?></td>
              <td><?php echo $row['source_id']; ?></td>
              <td><?php echo $row['email']; ?></td>
              <td><?php echo $customer; ?></td>
              <td><?php echo date("m/d/Y", strtotime($row["created"])); ?></td>
              <td><?php if($row['login']!=NULL){echo date("m/d/Y",$row['login']);} ?></td>
              <td><?php if($row['active']==1){echo "Yes";}else{echo "No";} ?></td>
              <td><?php echo user::get_role_name($row['rid']); ?></td>
              <td><?php 
                if($row['cash_incentive']==1){echo "Cash";}else{echo "Regular";} ?>
                </td>
              <td><a href='user-edit?uid="<?php echo $row['uid']; ?>"'>View </a></td>
              <td><a href='switch?email="<?php echo $row['email']; ?>"'> Switch</a></td>
              <td><input type='checkbox' name='email-list[]' value='<?php echo $row['email']; ?>'></td>
            </tr>   
          <?php }
        }
      ?>

原因

columns选项指定的数组中的项目数应与<td>元素的数量相匹配。您有columns个数组中的12个元素和13个<td>元素。

来自manual：

请注意，如果您使用columns来定义列，那么您必须在数组中为表格中的每一列添加一个条目（如果您没有这些列，则可以是null ; t指定任何选项。）

解

将额外对象添加到columns数组以匹配HTML中的列数。

或者，您可以完全将columns替换为columnDefs以提高可读性。

"columnDefs": [{
      "orderable": false,
      "searchable": false,
      "targets": [0]
   }, {
      "orderable": false,
      "targets": [2, 3, 11, 12]
   }
],
