The example in this article describes how jQuery implements Table header sorting with grouped data. Share it with everyone for your reference, the details are as follows:

As shown below:

Requirement: When clicking on the table header to sort, the data hierarchical relationship between "Group" and "Group Details" remains unchanged

I found a regular table sorting from the Internet, modified it to meet the "group support", and posted it here for backup

&lt;head&gt;
 &lt;meta http-equiv="Content-Type" content="text/html; charset=gb2312" /&gt;
 &lt;style type="text/css"&gt;
  .tbl-list, .tbl-list td, .tbl-list th {
   border: solid 1px #000;
   border-collapse: collapse;
   padding: 10px;
   margin: 15px;
  }
 &lt;/style&gt;
 &lt;script type="text/javascript" src="jquery.min.js"&gt;&lt;/script&gt;
 &lt;title&gt;table sort&lt;/title&gt;
 &lt;script type="text/javascript"&gt;
  //排序 tableId: 表的id,iCol:第几列 ；dataType：iCol对应的列显示数据的数据类型
  function sortAble(th, tableId, iCol, dataType) {
   var ascChar = "▲";
   var descChar = "▼";
   var table = document.getElementById(tableId);
   //排序标题加背景色
   for (var t = 0; t &lt; table.tHead.rows[0].cells.length; t++) {
    var th = $(table.tHead.rows[0].cells[t]);
    var thText = th.html().replace(ascChar, "").replace(descChar, "");
    if (t == iCol) {
     th.css("background-color", "#ccc");
    }
    else {
     th.css("background-color", "#fff");
     th.html(thText);
    }
   }
   var tbody = table.tBodies[0];
   var colRows = tbody.rows;
   var aTrs = new Array;
   //将得到的行放入数组，备用
   for (var i = 0; i &lt; colRows.length; i++) {
    //注：如果要求“分组明细不参与排序”，把下面的注释去掉即可
    //if ($(colRows[i]).attr("group") != undefined) {
     aTrs.push(colRows[i]);
    //}
   }
   //判断上一次排列的列和现在需要排列的是否同一个。
   var thCol = $(table.tHead.rows[0].cells[iCol]);
   if (table.sortCol == iCol) {
    aTrs.reverse();
   } else {
    //如果不是同一列，使用数组的sort方法，传进排序函数
    aTrs.sort(compareEle(iCol, dataType));
   }
   var oFragment = document.createDocumentFragment();
   for (var i = 0; i &lt; aTrs.length; i++) {
    oFragment.appendChild(aTrs[i]);
   }
   tbody.appendChild(oFragment);
   //记录最后一次排序的列索引
   table.sortCol = iCol;
   //给排序标题加“升序、降序” 小图标显示
   var th = $(table.tHead.rows[0].cells[iCol]);
   if (th.html().indexOf(ascChar) == -1 && th.html().indexOf(descChar) == -1) {
    th.html(th.html() + ascChar);
   }
   else if (th.html().indexOf(ascChar) != -1) {
    th.html(th.html().replace(ascChar, descChar));
   }
   else if (th.html().indexOf(descChar) != -1) {
    th.html(th.html().replace(descChar, ascChar));
   }
   //重新整理分组
   var subRows = $("#" + tableId + " tr[parent]");
   for (var t = subRows.length - 1; t &gt;= 0 ; t--) {
    var parent = $("#" + tableId + " tr[group='" + $(subRows[t]).attr("parent") + "']");
    parent.after($(subRows[t]));
   }
  }
  //将列的类型转化成相应的可以排列的数据类型
  function convert(sValue, dataType) {
   switch (dataType) {
    case "int":
     return parseInt(sValue, 10);
    case "float":
     return parseFloat(sValue);
    case "date":
     return new Date(Date.parse(sValue));
    case "string":
    default:
     return sValue.toString();
   }
  }
  //排序函数，iCol表示列索引，dataType表示该列的数据类型
  function compareEle(iCol, dataType) {
   return function (oTR1, oTR2) {
    var vValue1 = convert(removeHtmlTag($(oTR1.cells[iCol]).html()), dataType);
    var vValue2 = convert(removeHtmlTag($(oTR2.cells[iCol]).html()), dataType);
    if (vValue1 &lt; vValue2) {
     return -1;
    }
    else {
     return 1;
    }
   };
  }
  //去掉html标签
  function removeHtmlTag(html) {
   return html.replace(/&lt;[^&gt;]+&gt;/g, "");
  }
  //jQuery加载完以后，分组行高亮背景，分组明细隐藏
  $(document).ready(function () {
   $("tr[group]").css("background-color", "#ff9");
   $("tr[parent]").hide();
  });
  //点击分组行时，切换分组明细的显示/隐藏
  function showSub(a) {
   var groupValue = $(a).parent().parent().attr("group");
   var subDetails = $("tr[parent='" + groupValue + "']");
   subDetails.toggle();
  }
 &lt;/script&gt;
