How can i make a specific row bold?

I am working on generating a pdf and till now its going fine, but i want some specific rows to be bold. for example see picture : grid template from jspdf-autotable How can i make for example, row with id =1 and id=3 bold? Below my code.

function createPDF() {
            if(vm.activeCompanyYear){
                var url = "/coci/report/registry/"+vm.activeCompanyYear;

                DataApiService.callApi(url,null,"GET").then(function(reportData){

                    if(reportData){
                        var doc = new jsPDF('p', 'pt');
                        var row = 45;
                        addPdfHeader(doc, row, "");
                        doc.printingHeaderRow = true;
                        var columns = [ "Description", vm.activeCompanyYear,vm.activeCompanyYear-1, vm.activeCompanyYear-2,vm.activeCompanyYear-3,vm.activeCompanyYear-4,"% t.o.v.'13" ];

                        var rows = [];

                        for(var j=0; j<reportData.length; j++){
                            var obj = reportData[j];

                            if (!obj.description ) {obj.description = '';}

                            if (!obj.year5 ) {obj.year5 = '';}

                            if (!obj.year4 ) {obj.year4 = '';}

                            if (!obj.year3 ) {obj.year3 = '';}

                            if (!obj.year2 ) {obj.year2 = '';}

                            if (!obj.year1 ) {obj.year1 = '';}

                            if (!obj.delta ) {obj.delta = '';}


                            /*TODO : Align data right in grid*/

                            var singleRow = [obj.description,obj.year5,obj.year4,obj.year3,obj.year2,obj.year1,obj.delta];
                            rows.push(singleRow);

                        }                       

                        doc.autoTable(columns, rows, {
                            theme : 'grid',
                            styles: {
                                    halign: 'right',
                                     },
                            headerStyles: {
                                         fillColor: [33, 150, 243],
                                         halign:'center'
                            },
                            margin : {
                                top : 100
                                },
                            columnStyles:{
                                 0: {halign:'left'}
                            }

                        });


                        vm.isLoading = false;
                        blockUI.stop();
                        /* doc.save(); */
                        vm.reportData = doc.output('datauristring');

                    }
                });
            }
        }

Something like this should work:

autoTable(doc, {
  html: '#table',
  didParseCell: function(cell, data) {
    if (data.row.index === 0 || data.row.index === 2) {
      cell.styles.fontStyle = 'bold';
    }
  }
})
