我正在使用 jQuery DataTables，我想知道是否可以禁用表格第一列的自动排序？

我的代码如下所示：

        /* Default class modification */
        $.extend( $.fn.dataTableExt.oStdClasses, {
            "sWrapper": "dataTables_wrapper form-inline"
        } );

        /* API method to get paging information */
        $.fn.dataTableExt.oApi.fnPagingInfo = function ( oSettings )
        {
            return {
                "iStart":         oSettings._iDisplayStart,
                "iEnd":           oSettings.fnDisplayEnd(),
                "iLength":        oSettings._iDisplayLength,
                "iTotal":         oSettings.fnRecordsTotal(),
                "iFilteredTotal": oSettings.fnRecordsDisplay(),
                "iPage":          Math.ceil( oSettings._iDisplayStart / oSettings._iDisplayLength ),
                "iTotalPages":    Math.ceil( oSettings.fnRecordsDisplay() / oSettings._iDisplayLength )
            };
        }

        /* Bootstrap style pagination control */
        $.extend( $.fn.dataTableExt.oPagination, {
            "bootstrap": {
                "fnInit": function( oSettings, nPaging, fnDraw ) {
                    var oLang = oSettings.oLanguage.oPaginate;
                    var fnClickHandler = function ( e ) {
                        e.preventDefault();
                        if ( oSettings.oApi._fnPageChange(oSettings, e.data.action) ) {
                            fnDraw( oSettings );
                        }
                    };

                    $(nPaging).addClass('pagination').append(
                        '<ul>'+
                            '<li class="prev disabled"><a href="#">&larr; '+oLang.sPrevious+'</a></li>'+
                            '<li class="next disabled"><a href="#">'+oLang.sNext+' &rarr; </a></li>'+
                        '</ul>'
                    );
                    var els = $('a', nPaging);
                    $(els[0]).bind( 'click.DT', { action: "previous" }, fnClickHandler );
                    $(els[1]).bind( 'click.DT', { action: "next" }, fnClickHandler );
                },

                "fnUpdate": function ( oSettings, fnDraw ) {
                    var iListLength = 5;
                    var oPaging = oSettings.oInstance.fnPagingInfo();
                    var an = oSettings.aanFeatures.p;
                    var i, j, sClass, iStart, iEnd, iHalf=Math.floor(iListLength/2);

                    if ( oPaging.iTotalPages < iListLength) {
                        iStart = 1;
                        iEnd = oPaging.iTotalPages;
                    }
                    else if ( oPaging.iPage <= iHalf ) {
                        iStart = 1;
                        iEnd = iListLength;
                    } else if ( oPaging.iPage >= (oPaging.iTotalPages-iHalf) ) {
                        iStart = oPaging.iTotalPages - iListLength + 1;
                        iEnd = oPaging.iTotalPages;
                    } else {
                        iStart = oPaging.iPage - iHalf + 1;
                        iEnd = iStart + iListLength - 1;
                    }

                    for ( i=0, iLen=an.length ; i<iLen ; i++ ) {
                        // Remove the middle elements
                        $('li:gt(0)', an[i]).filter(':not(:last)').remove();

                        // Add the new list items and their event handlers
                        for ( j=iStart ; j<=iEnd ; j++ ) {
                            sClass = (j==oPaging.iPage+1) ? 'class="active"' : '';
                            $('<li '+sClass+'><a href="#">'+j+'</a></li>')
                                .insertBefore( $('li:last', an[i])[0] )
                                .bind('click', function (e) {
                                    e.preventDefault();
                                    oSettings._iDisplayStart = (parseInt($('a', this).text(),10)-1) * oPaging.iLength;
                                    fnDraw( oSettings );
                                } );
                        }

                        // Add / remove disabled classes from the static elements
                        if ( oPaging.iPage === 0 ) {
                            $('li:first', an[i]).addClass('disabled');
                        } else {
                            $('li:first', an[i]).removeClass('disabled');
                        }

                        if ( oPaging.iPage === oPaging.iTotalPages-1 || oPaging.iTotalPages === 0 ) {

将aaSorting选项设置为空数组。它将禁用初始排序，同时在您单击列时仍允许手动排序。

"aaSorting": []

aaSorting 数组应包含每个要排序的列的数组，该数组最初包含列的索引和方向字符串（'asc' 或 'desc'）。

在较新版本的数据表（1.10.7 版）中，情况似乎发生了变化。防止 DataTables 自动按第一列排序的方法是将order选项设置为空数组。

您只需将以下参数添加到 DataTables 选项：

"order": []

如下设置您的 DataTable 以覆盖默认设置：

$('#example').dataTable( {
    "order": [],
    // Your other options here...
} );

这将覆盖默认设置"order": [[ 0, 'asc' ]]。

您可以在此处找到有关该order选项的更多详细信息。

var table;

$(document).ready(function() {

    //datatables
    table = $('#userTable').DataTable({ 

        "processing": true, //Feature control the processing indicator.
        "serverSide": true, //Feature control DataTables' server-side processing mode.
        "order": [], //Initial no order.
         "aaSorting": [],
        // Load data for the table's content from an Ajax source
        "ajax": {
            "url": "<?php echo base_url().'admin/ajax_list';?>",
            "type": "POST"
        },

        //Set column definition initialisation properties.
        "columnDefs": [
        { 
            "targets": [ ], //first column / numbering column
            "orderable": false, //set not orderable
        },
        ],

    });

});

放

"targets": [0]

到

 "targets": [ ]

this.dtOptions = {
    order: [],
    columnDefs: [ {
        'targets': [0], /* column index [0,1,2,3]*/
        'orderable': false, /* true or false */
    }],
    ........ rest all stuff .....
}

以上对我来说很好。

（我正在使用 Angular 版本 7、angular-datatables 版本 6.0.0 和引导程序版本 4）

使用这个简单的代码进行 DataTables 自定义排序。它的 100% 工作

<script>
    $(document).ready(function() {
        $('#myTable').DataTable( {
            "order": [[ 0, "desc" ]] // "0" means First column and "desc" is order type; 
        } );
    } );
</script>


参见数据表网站

添加

"aaSorting": []

并检查默认值是否null不仅设置了可排序列 

if ($('#table').DataTable().order().length == 1) {
    d.SortColumn = $('#table').DataTable().order()[0][0];
    d.SortOrder = $('#table').DataTable().order()[0][1];
}

如果任何其他解决方案都无法修复它，请尝试覆盖样式以隐藏排序切换器：

.sorting_asc:after, .sorting_desc:after {
  content: "";
}
