I'm experiencing a problem when loading the data from my database, the data is somewhat large enough to cause a delay.
I tried to add this in my code, but still not enough.
.fixed-table {
table-layout: fixed;
}
I stumbled upon this guide. https://patdavid.net/2019/02/displaying-a-big-html-table/. So i tried to implement it, unfortunately my loading time is still the same.
With this line, how will I approach this
I set the table to display: none; initially and once the document was ready I set it back to display: table; (relying on JavaScript to do this).
This is my table script
/* FOR CORPORATE DATA TABLE START */
function format ( dataSource ) {
var html = '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;" class="fixed-table table table-bordered">';
for (var key in dataSource){
html += '<tr>'+
'<td>' + key +'</td>'+
'<td>' + dataSource[key] +'</td>'+
'</tr>';
} return html += '</table>'; }
var earnings_amendment_table = $('#earnings_amendment').DataTable({});
// Add event listener for opening and closing details
$('#earnings_amendment').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = earnings_amendment_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({
'Particulars : ' : tr.data('key-1'),
'Account Type : ' : tr.data('key-2'),
'Date Due : ' : tr.data('key-3')
})).show();
tr.addClass('shown');
} });
/* FOR CORPORATE DATA TABLE END */
This is the table
<div class="box-body">
<table id="earnings_amendment" class="fixed-table table table-bordered">

<th>Employee Name</th>

The total data being loaded is around 300,000-500,000. It's taking so long for it to load. up to 60-70 seconds. Is there a way for us to reduce this time? Is the structure of my table/query wrong, is there any possible solution to reduce this delay?
I tried to use clusterize.js, but I can't seem to be able to implement it.
ADDENDUM: Is there a way for this to be implemented into SQL SERVER 2012?https://github.com/DataTables/DataTables/blob/master/examples/server_side/scripts/server_processing.php
I'm planning to do this via Server-Side, but I'm worried that I may change all the tables that I did.
