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 created two samples in this FIDDLE.

If you want to use objects in rows add you should add columns in your datatable init:

JS

var table3 = $('#exampleTable').DataTable({
    data:[{ "Year": "2012", "Month": "January", "Savings": "$100" },
      { "Year": "2012", "Month": "February", "Savings": "$80" }],
    columns:[{data: 'Year'},
        {data: "Month"},
        {data: "Savings"}]
}); 

but if you don't want to do this you can use next syntax in rows add:

JS

table4.rows.add(
   [[ "Tiger Nixon", "System Architect","$3,120" ],
     ["Tiger Nixon", "System Architect", "$3,120" ]]
).draw(); 

Look fiddle it's more informative.
