    Disable the deferRender option. It is enabled in DataTables 2 and causes the row nodes to be created only when needed by a draw action. Disabling it (deferRender: false) will cause the row node and cells to be created immediately.

    Your first code snippet, without draw(), works with DT 2.0.3 in this test case:

    Note deferRender is set false.

    Please provide a link to a test case showing the issue.

    console.log ->
    <tr><td>Tiger Nixon1</td><td>Javascript Developer</td><td>New York</td><td>33</td><td>2012/12/02</td><td>$4,080</td></tr>

    example
    table config
    ...
    comlumns: [
    {
    title: "title",
    data: "colulm1",
    className: "text-end",
    },
    ]
    ...

    after row.add()
    want value =>
    <tr><td class="text-end">some data</td><td>

    but that returns
    <tr><td>some data</td><td>

    I built a test case for you to show the issue.
    https://live.datatables.net/taxareri/2/edit

    It shows the missing className if the row is not added to the current page. But the row is displayed on the page.

    I also noticed a bit different behavior with DOM sourced table. The added rows aren't displayed on the page. It requires calling draw() to add the rows to the page. The row on the current page displays the className but the row not on the page still does not.

    I added the draw event to both test cases. It seems the ajax loaded test case there is a call to draw() at some point after the rows are added. Not sure what is triggering this draw() call.

    @allan will need to take a look.
