数据表中的多列排序

Question

我有一张桌子，它有 8 列。假设他们的标题即'A'，'B'.....'H'。

我想应用多列排序，例如：

默认视图：案例1：如果用户点击'A'然后将列排序为'A'（desc）->'B'（asc）->'E'（asc）->....-> “H”（升序）

如果用户再次点击“A”，那么什么都不会发生。

案例2：如果用户点击'E'然后将列排序为'E'（asc）->'A'（desc）->'B'（asc）->'F'（asc）-> .... - > 'H' (asc)

如果用户再次点击“E”，则不会发生任何事情。

案例3：如果用户点击'F'然后将列排序为'F'（asc）->'A'（desc）->'B'（asc）->'E'（asc）-> .... - > 'H' (asc)

如果用户再次点击“F”，那么什么都不会发生。

请看我所做的代码

$(document).ready(function() {
  window.history.pushState("object or string", "EPAP|AuctionList", contextPath+"/auctions/auctionlist");
  languageList.sEmptyTable = '<spring:message code="auctionlist.emptytable"/>';

  auctionTable = $('#datatable').DataTable({     
    language: languageList,
    order: [[0, 'desc']],
    columnDefs: [
        {targets: 0, orderSequence: ['desc']},
        {targets: 1, orderSequence: ['asc']},
        {targets: 4, orderSequence: ['asc']},
        {targets: 5, orderSequence: ['asc']},
        {targets: 6, orderSequence: ['asc']},
        {targets: 7, orderSequence: ['asc']},           
        {type: "datetime-moment",targets: 5}
    ],

    initComplete: function () {
        $('#datatable th').on('click', function (event) {

            var auctionTable = $('#datatable').DataTable();
            var th = $(this).closest('th');
            var colIndex = auctionTable.column( th ).index();
            console.log(colIndex);

            if (colIndex === 0) {
                console.log('order col 0 ')
                auctionTable.order([[0, 'desc'], [1, 'asc'], [4, 'asc'], [5, 'asc'],[6, 'asc'],[7, 'asc']]).draw();
            }else if (colIndex === 4) {
                console.log('order col 4 ')
                auctionTable.order([[4, 'asc'],[0, 'desc'], [1, 'asc'], [5, 'asc'],[6, 'asc'],[7, 'asc']]).draw();
                }else if (colIndex === 5) {
                    console.log('order col 5 ')
                    auctionTable.order([[5, 'asc'],[0, 'desc'], [1, 'asc'],[4, 'asc'] ,[6, 'asc'],[7, 'asc']]).draw();
                    }else if (colIndex === 6) {
                        console.log('order col6 ')
                        auctionTable.order([[6, 'asc'],[0, 'desc'], [1, 'asc'], [5, 'asc'],[4, 'asc'],[7, 'asc']]).draw();
                        }else if (colIndex ===7) {
                            console.log('order col 7')
                            auctionTable.order([[7, 'asc'],[0, 'desc'], [1, 'asc'], [5, 'asc'],[4, 'asc'],[6, 'asc']]).draw();
                            }          

        });     
    },  

    "aoColumnDefs": [
      { "bSortable": false, "aTargets": [ 2,3,8 ] }
    ] ,

    "ajax": {
      "url": (contextPath + "/auctions/dailyAuctionViewList"),
      "cache": false,
      "asyc":false,
      "dataSrc": ""
    },

输出：

我想要什么？：

1. 开始时间应按“升序”顺序，但用户不能申请使用开始时间进行排序。
2. 默认视图：我表示使用列索引而不是列名 [ [0, 'desc'], [1, 'asc'], [4, 'asc'], [5, 'asc'],[6, 'asc'],[7, 'asc'] ]

前 0 个索引列排序，然后是 1 个索引，依此类推

1. 如果用户点击第 4 个索引，则 [[4, 'asc'],[0, 'desc'], [1, 'asc'], [5, 'asc'],[6, 'asc'] ,[7, 'asc']]
2. 第5个索引，[[5, 'asc'],[0, 'desc'], [1, 'asc'],[4, 'asc'] ,[6, 'asc'],[7, 'asc']] 和第 6 和第 7 索引相同

但输出图像中的列排序不正确。

我找到了解决办法：

$(document).ready(function() {

  var auctionTable = $('#datatable').DataTable({
    order:[[0, 'desc']],
    columnDefs: [
        {targets: 0, orderSequence: ['desc']},
        {targets: 1, orderSequence: ['asc']},
        {targets: 4, orderSequence: ['asc']},
        {targets: 5, orderSequence: ['asc']},
        {targets: 6, orderSequence: ['asc']},
        {targets: 7, orderSequence: ['asc']}, 
        {orderable: false, targets:[1,2,3,8]}   
    ] 
 }); });
