    You can use the Select Extension to select the row if you like. Or you can use your own highlighting technique.

    Use row().delete() to delete the row.

    The key is being able to select the first row in the table. The row-selector is used to select the appropriate row. To get the first row you would use a jQuery selector like this: row(':eq(0)').

    I have a table like this;
    var dtable = $('#table').DataTable(
                {
    
                 data : data.events,
    
        columns: [
    
          { data: 'name',  title: 'Person Name'  },
          { data: 'action', title: 'Event'  },
          { data: 'date', title: 'Date' }
    

    ]

                });
    

    And i use this method but it doesn't work. :(

    $( dtable.row(':eq(0)')).addClass( 'highlight' );

    My css method is this :

          td.highlight {
        background-color: whitesmoke !important;
          }

    You need to use row().node() like this:
    `$( dtable.row(':eq(0)').node()).addClass( 'highlight' );

    td.highlight won't work because you are applying the class to the row not cells. Highlighting Datatables rows is a bit tricky due to its styling. See CSS tab of this example:

    dtable.row( 0 ).delete();
    this method doesnt work and it gives me "Uncaught TypeError: dtable.row(...).delete is not a function" error. What am i doing wrong?

    I'm full of mistakes today :smile:

    I gave the wrong link to show the highlighting:
    http://live.datatables.net/sinazeca/2/edit

    Also the API is row().remove() not delete(). See the example for remove().
