如何创建具有多个子行（嵌套表）的 jQuery 数据表？

问题：我需要创建一个具有嵌套表格式的表。当用户单击加号按钮时，它应该显示嵌套表。如果他们点击减号按钮，它应该隐藏。

我已经完成了jquery datatable，它工作正常。但我无法显示子表的多行。我已经尝试了很多次，但无法显示正确的格式。

这是我提到的创建表的链接https://datatables.net/examples/api/row_details.html https://datatables.net/examples/api/row_details.html

Database: Actual data coming from the database as per the below format and I have converted JSON format to display :

C# Code:

 return new JsonResult { Data = new { data = test }, JsonRequestBehavior = 
JsonRequestBehavior.AllowGet };

I need an output like this with a nested table:

UI CODE:

/* Formatting function for row details - modify as you need */
 function format ( d ) {
   // `d` is the original data object for the row
  return '<table cellpadding="5" cellspacing="0" border="0" style="padding- 
left:50px;">'+
      '<tr>' +
            '<td>City Name</td>' +
            '<td>Permission</td>' +
        '</tr><tr>' +
            '<td>' + d.City+ '</td>' +
            '<td>' + d.Permission+ '</td>' +
        '</tr>' +
'</table>';
}

$(document).ready(function() {
var table = $('#example').DataTable( {
    "ajax": "../ajax/data/objects.txt",
    "columns": [
        {
            "className":      'details-control',
            "orderable":      false,
            "data":           null,
            "defaultContent": ''
        },
        { "data": "UserName" },
        { "data": "Email" },
        { "data": "UserId" },

    ],
    "order": [[1, 'asc']]
} );

// Add event listener for opening and closing details
$('#example tbody').on('click', 'td.details-control', function () {
    var tr = $(this).closest('tr');
    var row = table.row( tr );

    if ( row.child.isShown() ) {
        // This row is already open - close it
        row.child.hide();
        tr.removeClass('shown');
    }
    else {
        // Open this row
        row.child( format(row.data()) ).show();
        tr.addClass('shown');
    }
  } );
 } );

JSON 格式：

{"data":[
{"UserId":"ABC","UserName":"Peter","Email":"[email protected] /cdn-cgi/l/email-protection","CityName":"Chennai","Permission":"Manager,LocalUser"},
{"UserId":"ABC","UserName":"Peter","Email":"[email protected] /cdn-cgi/l/email-protection","CityName":"Bangalore","Permission":"Admin,LocalUser"},
{"UserId":"xyz","UserName":"Haiyan","Email":"[email protected] /cdn-cgi/l/email-protection","CityName":"Bangalore","Permission":"LocalUser"},
{"UserId":"xyz","UserName":"Haiyan","Email":"[email protected] /cdn-cgi/l/email-protection","CityName":"Chennai","Permission":"LocalUser,Manager"}]}

使用技术：ASP.Net MVC5

我准备使用 linq 或修改 JSON 数据格式的任何其他方式。

您可以像这样将 Id 提供给您的子表

function format ( d ) {
   // `d` is the original data object for the row
  return '<table id="childtable" cellpadding="5" cellspacing="0" border="0" style="padding- 
left:50px;">'+
      '<tr>' +
            '<td>City Name</td>' +
            '<td>Permission</td>' +
        '</tr><tr>' +
            '<td>' + d.City+ '</td>' +
            '<td>' + d.Permission+ '</td>' +
        '</tr>' +
'</table>';
}

并执行与父表相同的操作

var childTable = $('#childtable').DataTable( {
    "ajax": "../ajax/data/objects.txt",
    "columns": [

    ],
    "order": [[1, 'asc']]
} );

在 columns 部分绑定您的 json 对象。
