how to add data in datatable?

I am trying to add data dynamically in datatable.I have initialized table on document.ready and created an instance of it.After that, I am trying to add data in the table using instance.
$(document).ready(function() {
//Initialize tooltips
table_sgdFile_list_linked = $('#sgdFile_list_linked').DataTable({
bSort: false,
destroy:true,
bLengthChange: false,
pageLength: 4,
columns: [{
title: "Name"
},
{
title: "Action"
}
]
});
});
I am trying to bind the data
table_sgdFile_list_linked.data(dataSet)
but it is not working.

my_list = $('#my-table-html-id').DataTable( {
"processing": true,
"serverSide": false,
"paging": true,
"bLengthChange" : true,
"bFilter": false,
"pageLength": 10,
"info": false,
"ordering": true,
"ajax": "PATH-OF-MY-API",
"columnDefs": [
{
"render": function ( data, type, row ) {
var html = data + " Modified!";
return html;
},
"orderable": false,
"targets": 1 //Last column
},
],
})

you can try this:
to add 1 row: table_sgdFile_list_linked.row.add(rowJson).draw();
to add multiple rows: table_sgdFile_list_linked.rows.add(rowsJson).draw();

following worked for me :
table_sgdFile_list_linked.clear().draw();
$('#sgdFile_list_linked').dataTable().fnAddData(trHTML);

DataTables - scrollX causing squashed header

So I'm using DataTables with the scrollX parameter set to true, however it's causing the thead columns to collapse.
Note: the datatable is appearing inside a Bootstrap Modal as part of a react project.
How can I resolve this?
When I click on one of the columns, causing it to refresh, it fixes itself. Also, if I remove the scrollX it also doesn't collapse.
Initialisation code:
$('#item-search').DataTable( {
ajax: {
"data": {
type: "map_items",
map_id: this.map_id
},
"dataSrc": (r) => {
console.log(r);
return r.data;
},
type: "POST",
url: "src/php/search.php"
},
autoWidth : false,
columns: [
{
"data": "brand"
},
{
"data": "name"
},
{
"data": "quantity"
},
{
"data": "measurement"
},
{
"data": "type"
},
],
dom: 'rtlip',
language: {
"info": "Showing page _PAGE_ of _PAGES_",
"infoFiltered": ""
},
lengthMenu: [ 1, 2, 3 ],
pageLength: 1,
processing: true,
responsive: true,
scrollX: true,
select: {
style: "multi"
},
serverSide: true
});

In data table initialization include following property.
autoWidth : true
Along with add this
"fnInitComplete": function(oSettings) {
$( window ).resize();
}
"fnDrawCallback": function(oSettings) {
$( window ).trigger('resize');
}

DataTable should be initialized with the following code to achieve horizontal scrolling:
"sScrollX": "100%",
"sScrollXInner": "110%",
"bScrollCollapse": true,
"fixedColumns": {
"leftColumns": 1
}

This work in my angular project
this.dtTarifas = {
scrollX: true,
autoWidth: false,
lengthChange: false,
responsive: false
}
I have in my package.json "angular-datatables": "7.0.0"

$('#DataTableID').DataTable({
//"scrollX": true,
"initComplete": function (settings, json) {
$("#DataTableID").wrap("<div style='overflow:auto; width:100%;position:relative;'></div>");
},
});

jquery datatable binding data property to content that is displayed

I have my jQuery datatable plugin installed and I've initialized it like this:
$('#datatable-responsive2').DataTable({
// data: data,
// deferRender: true,
"pageLength": 25,
"bLengthChange": false,
"processing": true,
"serverSide": true,
"filter": false,
"orderMulti": false,
"ajax": {
"url": "/Administrator/LoadData/",
"type": "POST",
"datatype":"json"
},
"columns": [
{ "data": "FirstName", "name": "Lela", "autoWidth": true },
{ "data": "Email", "name": "Email", "autoWidth": true },
{ "data": "Active", "name": "Status", "autoWidth": true },
{ "targets": -1, "data": "UserId", "defaultContent": "<button>Click!</button>", "autoWidth": true },
{ "data": "FirstName", "name": "Full name", "autoWidth": true }
]
});
Please note this column:
{ "targets": -1, "data": "UserId", "defaultContent": "<button>Click!</button>", "autoWidth": true }
I've followed their documentation on how to render an HTML element there... But what I need now and wasn't able to figure how do I actually set a certain attribute for this HTML element inside the datatable when its being generated...
As u can see I've set data source for the datatable as UserId, and now I'd like each button "Click" to have value whatever the value of UserId is...
Can someone help me out?
P.S. so I want to output an HTML element in that column whos structure would be something like this:
<button values="whatever the value of userId is..?">Click me event</button>

You would need to define the render property of the column for that which would be the following :
{
"targets": -1,
"data": "UserId",
"render": function (data, type, full, meta) {
return "<button id='"+ data +"'>Click!</button>";
},
"autoWidth": true
}
The data property will be containing UserId in it which can be used in the render function.
You can refer to the documentation of it here

Hide columns not working properly with server side processing in jquery datatables

I am using jquery datatables(1.10.9) with server side processing.
tab = $('#'+div).dataTable( {
"sDom": 'T<"clear">frltip',
"aaSorting": [],
"bAutoWidth" : false,
"sPaginationType": "full_numbers",
"sScrollY": "550px",
"sScrollX": "100%",
"bFilter": true,
"aoColumnDefs": [{ "bSearchable": false, "aTargets": [ 2 ] },{ "bSortable": false, "bSearchable": false, "aTargets": [ 12 ] },{ "bSortable": false, "bSearchable": false, "aTargets": [ 13 ] }],
"oTableTools": {},
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": 'data/getdata',
"fnServerParams": function ( aoData ) {
},
"fnRowCallback": function( nRow, aData, iDisplayIndex ){
// Processing data like:
// $('td:eq(2)', nRow ).html( 'Test' );
}
});
// Hiding 5th column
tab.fnSetColumnVis( 5, false); //Does not work.Removes the column header but not the row data.
How do I get hide column to work properly with server side processing in jquery datatables?

I got this to work as follows:
fnDrawCallback: function() {
$('td:nth-child(3),th:nth-child(3)').hide();
}]
tab.fnSetColumnVis( 3, false) will not work because it re-fetches the data.Hence, had to do it using simple old jquery.

fnSetColumnVis() function has 3rd property (true or false) that not rebind the data. so try with fnSetColumnVis(3,false,flase) may be it can help.

You do it when you set up the datatable, using "ColumnDefs" thusly, where targets is the number of the column you want to hide:
tab = $('#'+div).dataTable( {
"columnDefs": [{ targets: 5, visible: false }],
"sDom": 'T<"clear">frltip',
"aaSorting": [],
"bAutoWidth" : false,
...
If you have 2 hidden columns, it will look like this:
"columnDefs": [{ targets: 5, visible: false }, { targets: 6, visible: false }],
Note: column numbering starts at 0.

Push AJAX retrieved JSON into Datatables

I'm using the datatables plugin and it's working fine for me. However, I'm making multiple calls to populate multiple tables, when I know I could make one AJAX call and store the results in a variable and have each table function use that variable for its data, but I can't get it to work.
I'm using something like to to get the data I need.
var all_data;
$.ajax({
async : false,
url: 'all_data.php',
type: 'GET',
success: function(data) {
all_data = data;
console.log(all_data);
}
})
The idea is to pass all_data variable into my table function (I have several on this one page) without having to make multiple calls. Doing the following returns one column with the letter "a", which isn't right. The data that comes back is JSON coded. I've used the below code, but with the AJAX function as part of the table function:
$("#my_table").DataTable({
"data":all_data
,
"paging": true,
"sDom": '<"top">t<"bottom"><"clear">',
"pageLength": 50,
"order": [[ 4, "desc" ]],
"aoColumns": [
{ "bSortable": true, "width": "0%", "sClass": "lang_body_2", "sTitle": "","visible":false },
{ "bSortable": true, "searchable": false, "width": "10%", "sClass": "lang_body_2 table_names", "sTitle": "" },
{ "bSortable": true, "searchable": false,"width": "20%", "sClass": "lang_body_2", "sTitle": "Database","visible":false},
{ "bSortable": true, "searchable": false ,"width": "20%","sClass": "lang_body_2","sTitle": "National Average","visible":false },
{ "bSortable": true, "searchable": false ,"width": "50%","sClass": "lang_body_2 index_num table_index","sTitle": "" },
],
"columns": [
{ "searchable": true },
{ "searchable": false },
{ "searchable": false },
{ "searchable": false },
{ "searchable": false },
],
"search": {
"search": "gen"
},
"columns": [
{ "width": "20%" },
null,
null,
null,
{ "width": "80%" },
],
"initComplete": function(settings, json) {
colorIndex();}
});
});
What am I doing wrong here? I'm suspecting I have to prepare all_data somehow, but I'm not sure what that might be.
EDIT: If I console.log the data returned, this is what I get (cut off for brevity):
Object {draw: 0, recordsTotal: 484, recordsFiltered: 484, data: Array[484]}
data: Array[484]
[0 … 99]
0: Array[5]
0: "edu"1: "High School"2: "37.90"3: "49.70"4: "76"length: 5

Your code looks fine, the only thing you need to do is
Assign your datatable to a variable and then in your ajax resolve clear, add data and draw the table.
var all_data;
$.ajax({
async : false,
url: 'all_data.php',
type: 'GET',
success: function(data) {
all_data = data;
console.log(all_data);
table.clear().row.add(all_data).draw(); //clear, add data and draw
}
});
// Assign your datatable to a variable
var table = $("#my_table").DataTable({
"data":all_data
,
"paging": true,
"sDom": '<"top">t<"bottom"><"clear">',
"pageLength": 50,
"order": [[ 4, "desc" ]],
"aoColumns": [
{ "bSortable": true, "width": "0%", "sClass": "lang_body_2", "sTitle": "","visible":false },
{ "bSortable": true, "searchable": false, "width": "10%", "sClass": "lang_body_2 table_names", "sTitle": "" },
{ "bSortable": true, "searchable": false,"width": "20%", "sClass": "lang_body_2", "sTitle": "Database","visible":false},
{ "bSortable": true, "searchable": false ,"width": "20%","sClass": "lang_body_2","sTitle": "National Average","visible":false },
{ "bSortable": true, "searchable": false ,"width": "50%","sClass": "lang_body_2 index_num table_index","sTitle": "" },
],
"columns": [
{ "searchable": true },
{ "searchable": false },
{ "searchable": false },
{ "searchable": false },
{ "searchable": false },
],
"search": {
"search": "gen"
},
"columns": [
{ "width": "20%" },
null,
null,
null,
{ "width": "80%" },
],
"initComplete": function(settings, json) {
colorIndex();}
});
});
