Hi, i am trying to color cells / rows in query report, the below code is working fine in v10. but its not working in v12.

code :

"formatter":function (row, cell, value, columnDef, dataContext, default_formatter) {
    value = default_formatter(row, cell, value, columnDef, dataContext);
	    if( == "Status"){
		    value = "<span style='font-weight: bold; color:white; background-color:black'>"+ value +"</span>";
