Check and Update column empty

antoniocib

Hi guys, I would like to check a column where when it is empty it must display "RITSIC" (without sending "RITSIC" to the database) instead when it is populated by the data taken from the database it must remain unchanged, I tried with rowCallback and with the function render directly in the columns but I couldn't, can you help me?

rowCallback: function ( row, data ) {       
    if ( data.start == ' ') {
            return "RITSIC";

}
},

AND

            {
                "data": "start",
                    render: function ( data, type, row ) {
                            if ( data.start == " ") {
                                    return 'RITSIC';
                            }
                        
                    },
                
            }

Sure, I updated my reply accordingly. The "else" is omittable.
