How to add multiple rows in datatables jquery

Question

I have used https://datatables.net/reference/api/rows.add%28%29 link working but the data showing the table as [object,object]. How to show the object to string

Answer 1

I came across this problem too - I found the documentation to be less than clear. Their example on https://datatables.net/reference/api/rows.add() does not work when I pass my own dynamically created array of objects.

In order to get it working, you have to specify the columns' names when instantiating DataTables.

In any case, the below is a working solution.

var DataTable = $('#tableName').DataTable({
  iDisplayLength: 15,   // number of rows to display
  columns: [
    { data: 'id' },
    { data: 'name' },
    { data: 'car' },
  ]
});

// assume this is a dynamically created array of objects
var persons = [
  {
    id: 1,
    name: 'John',
    car: 'Mercedes',
  }, 
  {
    id: 2,
    name: 'Dave',
    car: 'BMW',
  }, 
  {
    id: 3,
    name: 'Ken',
    car: 'Jeep',
  },  
];

DataTable.rows.add(persons).draw();
