JQGRID change the color of the line or data if the return is NULL or White

Question

Could I condition a different color if a column is blank in GRID?
Something like this: if Shop ="", red line color

 $table.jqGrid({
        url: url,
        datatype: 'json',
        mtype: 'GET',  
        postData: {
            representante: function () { return jQuery("#representante option:selected").val(); },
            vendedor: function () { return jQuery("#vendedor option:selected").val(); },
            nome: function () { return jQuery("#nome").val(); }
        }, 
       colModel: [
           { label: 'RECNO', name: 'RECNO', width: 80 },
           { label: 'Cliente', name: 'CLIENTE', width: 80 },
            { label: 'Loja', name: 'A1_LOJA', width: 80 },
            { label: 'Nome', name: 'A1_NOME', width: 350 },
            { label: 'CNPJ', name: 'A1_CGC', width: 120 },
            { label: 'Municipio', name: 'A1_MUN', width: 150 },
            { label: 'Telefone', name: 'A1_TEL', width: 80 },

        ],
         viewrecords: true,
            rowNum: 20,
            rowList: [20, 40, 100],
            height: "auto",
            //height: 400,
            emptyrecords: "Nenhum Cliente",
            loadtext: "Buscando e carregando...",
            //rowNum: 20,
            pager: "#jqGridPager",
            loadonce: true

    });

The image shown, would have to come with the second red line. Since it brought the two blank fields.

To whom it may interest, add in the event loadComplete and put your condition, picking up the line and changing its character

 loadComplete: function() {
             var rowIDs = jQuery("#jqGrid").getDataIDs();   //busca ids das linhas do grid

             for (var i = 0; i < rowIDs.length; i++) {     //entra nas linhas
                 var rowData = $("#jqGrid").jqGrid('getRowData', rowIDs[i]);   
                 //verifica se o campo está vazio (coloque sua condição)
                 if (rowData["A1_LOJA"] == "") {          
                        console.log("recno: ", rowData["RECNO"]);
                        // Muda a cor da Linha 
                        $(this).jqGrid('setRowData', rowIDs[i], false, {background:'#ee993d', color:'#fff'});
                 }
             }
          },
