Question

早上好，我在引导模式中使用Datatables时遇到了这个小问题，该模式应该显示一个SQLServer查询（只是一个选择），它必须能够打印为Excel文件或其他格式，但是我收到了控制台“ DataTables无法读取未定义的属性'aDataSort'的属性”中的错误，并且在该错误之前显示“ jquery-3.5.1.js：4055”，所以我认为这应该是问题。

由于我需要将结果导出为格式，因此发现了https://datatables.net/extensions/buttons/examples/initialisation/export.html

我正在阅读不同的网站，也似乎在这里，问题似乎是如何定义依赖关系，但是我尝试了不同的方式并且它不起作用，所以我不确定可能是什么问题...

这些是我的依赖项：

这是模态表

 <table id="table_to_show"></table>

这是应该显示该表的文件中的函数。

<script type="text/javascript">
        $(document).ready(function() {
    $('#table_to_show').DataTable( {
        dom: 'Bfrtip',
        buttons: [
            'copy', 'csv', 'excel', 'pdf', 'print'
        ]
        
    } );
} );
</script>

这是为SELECT生成的表本身：

$table="";

if ($result) {
    $data = sqlsrv_has_rows($result);
    if ($data === true)  {
        while ($data = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC)){

            $table=$table.'<tr>
            <td>'.$data['ID'].'</td>
            <td>'.$data['NAME'].'</td>
            <td>'.$data['LNAME'].'</td>
            <td>'.$data['number1'].'</td>
            <td>'.$data['number2'].'</td>
            <td>'.$data['MOBILE'].'</td>
            <td>'.$data['MRETIR'].'</td>
            </tr>';
        }
    }
}
    sqlsrv_close($conn);

    echo '<table class="table table-stripped">
    <thead>
    <th>Id</th>
    <th>Name</th>
    <th>Last Name</th>
    <th>Number 1</th>
    <th>Number 2</th>
    <th>Mobile #</th>
    <th>Retired?</th>
    </thead>
    <tbody>'.$table.'
    </tbody>';

这就是我所拥有的...有人可以帮助我解决这个问题吗？，我已经尝试解决2天，也许是3天...

预先感谢

尝试将json_encode用于PHP输出这是我的一些MYSQLI示例

  $sqlSelect = "SELECT * FROM table";
  $result = mysqli_query($conn, $sqlSelect);
        $someArray = [];
  if (mysqli_num_rows($result) > 0) {

while ($row = mysqli_fetch_array($result)) {
     array_push($someArray, [
  'ID'   => $row['ID'],
  'NAME' => $row['NAME'],
   'LNAME'   => $row['LNAME'],
  'ETC' => $row['ETC']
]);
}
}
 
 $json = json_encode($someArray);
echo ($json);

然后是The jQuery

 $.ajax({
            url: 'php_file.php',
            type: "GET",
            success: function(res){
                var obj = JSON.parse(res);
                console.log(obj);
                $('#table_to_show').DataTable({
                    dom: 'Bfrtip',
                    destroy: true,
                    processing: true,
                    "data"  : obj,  
                "columnDefs": [{
                "defaultContent": "-",
                "targets": "_all"
                    }], 
            buttons : [ 'copy', 'csv', 'excel', 'pdf', 'print' ],                   
                    "columns": [    
                        { "data": "ID" },
                        { "data": "NAME" },
                        { "data": "LNAME" },
                        { "data": "ETC" }
                    ]  
                 })

;
                    
                },
                error: function(xhr){
                    alert("Error Occured!", "error")
                }
            }); 
        
    
HTML

    <table id="table_to_show" class="display" style="width:100%">
        <thead>
            <tr>
                <th>ID</th>
                <th>NAME</th>
                 <th>LNAME</th>
                <th>ETC</th>   
            </tr>
        </thead>
    </table>
