How do I render numbers like 4999 to $4,999.00 in datatables? - datatables

Question

If the data source is from an existed DOM, rather than some JSON variable. How do I convert the numbers like 4999 to $4,999.00 in datatables?
I don't know what kind of options should be passed to the main function.
$('#example').DataTable(
{
// need help on this
}
);
Here is the code:
$(document).ready(function() {
//Only needed for the filename of export files.
//Normally set in the title tag of your page.
document.title='Simple DataTable';
// DataTable initialisation
$('#example').DataTable(
{
}
);
});

Answer 1

You can use the createdCell() callback, inside DataTables' columnDefs initializazion option.
Inside the callback, you have access to the <td> element of the created cell and to its data, so you can manipulate both in the way that you prefer.
In this fiddle I changed the shown data format using the Intl.NumberFormat() api:
$(document).ready(function() {
// Only needed for the filename of export files.
// Normally set in the title tag of your page.
document.title = 'Simple DataTable';
// DataTable initialisation
$('#example').DataTable({
columnDefs: [{
targets: 4, // <-- this is the target column
createdCell: function(cell, cellData, rowData, rowIndex, colIndex) {
const formattedContent = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD'
}).format(cellData);
cell.innerHTML = formattedContent;
},
}]
});
});
