DataTables warning: table id=table1 - Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3

Issue - DataTables warning: table id=table1 - Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3

Solution -

This error can often occur when trying to obtain a reference to the DataTable for working with the API. For example, you might have a function which will always try to create a DataTable instance by passing in options when created. Then you make a modification which calls this function on a table which has already been initialised and you get this error.

In such a case, you will want to use the $.fn.dataTable.isDataTable() static method. This can be used to check if a table is a DataTable or not already:

Javascript

if ( $.fn.dataTable.isDataTable( '#table1' ) ) {

    table = $('#table1').DataTable();

}

else {

    table = $('#table1').DataTable( {

        paging: false

    } );

}
