JQuery Datatable child row alignment not matching with parent column

Question

I really need your help in aligning the child row columns along with parent row columns. I found an example exactly matches what I did, So I am not putting the entire code here as there is a restriction in my company. So I am giving the reference here where the code/example is available. Example: JQuery Datatable with parent child relationship in same dataset. How to display it as parent child rows in the table?

I have attached the screenshot of the alignment. Can anyone please help. Note: I tried putting some CSS html table cellspacing/cellpadding, but it didn't workout.

var g_dataFull = [];

/* Formatting function for row details - modify as you need */
function format ( d ) {
    var html = '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;" width="100%">';
      
    var dataChild = [];
    var hasChildren = false;
    $.each(g_dataFull, function(){
       if(this.parent === d.name){
          html += 
            '<tr><td>' + $('<div>').text(this.name).html() + '</td>' + 
            '<td>' +  $('<div>').text(this.position).html() + '</td>' + 
            '<td>' +  $('<div>').text(this.office).html() +'</td>' + 
            '<td>' +  $('<div>').text(this.salary).html() + '</td></tr>';
         
          hasChildren = true;
       }
    });
  
    if(!hasChildren){
        html += '<tr><td>There are no items in this view.</td></tr>';
     
    }
  
 
    html += '</table>';
    return html;
}
 
$(document).ready(function() {
    var table = $('#example').DataTable( {
        "ajax": {
          "url": "https://api.myjson.com/bins/3mbye",
          "dataSrc": function(d){
            
             g_dataFull = d.data;
             var dataParent = []
             $.each(d.data, function(){
                if(this.parent === "null"){
                   dataParent.push(this);  
                }
             });
            
             return dataParent;

        ],
        "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');
        }
    } );
} );

Answer 1

If someone is still looking for answer then you need to add the $ to the child element HTML. Below is the example showing the same.

function format ( d ) {
  return $('<tr>'+
        '<td></td>'+
        '<td>'+d.name+'</td>'+
        '<td>'+d.position+'</td>'+
        '<td>'+d.office+'</td>'+
        '<td>'+d.extn+'</td>'+
        '<td>'+d.start_date+'</td>'+
        '<td>'+d.salary+'</td>'+
    '</tr>');
}

The $ after the return statement does the trick. For more reading you can visit the this thread from datatable.

Answer 2

Add this css:

table#example table {
    padding-left: 25px!important; /* maybe you put another value instead of 25 */
}

Try without using important first.

var g_dataFull = [];

/* Formatting function for row details - modify as you need */
function format ( d ) {
    var html = '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;" width="100%">';
      
    var dataChild = [];
    var hasChildren = false;
    $.each(g_dataFull, function(){
       if(this.parent === d.name){
          html += 
            '<tr><td>' + $('<div>').text(this.name).html() + '</td>' + 
            '<td>' +  $('<div>').text(this.position).html() + '</td>' + 
            '<td>' +  $('<div>').text(this.office).html() +'</td>' + 
            '<td>' +  $('<div>').text(this.salary).html() + '</td></tr>';
         
          hasChildren = true;
       }
    });
  
    if(!hasChildren){
        html += '<tr><td>There are no items in this view.</td></tr>';
     
    }
  
 
    html += '</table>';
    return html;
}
 
$(document).ready(function() {
    var table = $('#example').DataTable( {
        "ajax": {
          "url": "https://api.myjson.com/bins/3mbye",
          "dataSrc": function(d){
            
             g_dataFull = d.data;
             var dataParent = []
             $.each(d.data, function(){
                if(this.parent === "null"){
                   dataParent.push(this);  
                }
             });
