Hello, in the test mentioned below, those who write London in data[2] are in red. but what I want to do is have the columns with the same values ​​in data2 in red. for example, users with the same ip.

    Are you saying that you want to check for duplicates in the column and mark those red?

    Thanks for your help colin. But when I get the table information from sql, I get the following warning.

    "DataTables warning: table id=dataTable - Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3"

    yes, retrieve: true, does not give an warning when I do it. but this time the same columns are not red.

    Likely using retrieve: true is not the correct fix for your problem. Why are you initializing Datatatbles more than once? Please post your relevant JS code so we can take a look.

    I solved the problem. It was working 2 times because there was another code.

    $(document).ready(function() { var table = $('#example').DataTable(); $('#example tbody') .on( 'mouseenter', 'td', function () { var colIdx = table.cell(this).index().column; $( table.cells().nodes() ).removeClass( 'highlight' ); $( table.column( colIdx ).nodes() ).addClass( 'highlight' ); } ); } );
