angularjs - Change styles of specific column -


i have following declaration of table columns created dynamically: 

<table>   <tr ng-repeat="row in rows">       <td ng-class="{ 'tdhead' : $index == 0 }"                     ng-repeat="col in row.cols">{{col.val}}</td>        </tr> </table>

in example ng-class depends on row variable , changes td classes in first row. need change td classes in specific column. there way achieve this?

hope helps add below condition in ng-class

ng-class="{ 'tdhead' : $index == 0 && $parent.$index == 1 }"  

var app = angular.module('plunker', []);  app.controller('mainctrl',    function mainctrl($scope) {            $scope.rows = [{        name: "abc1",        empid: 10215,        cols: ["heading1", "heading2", "heading3"]      }, {        name: "abc2",        empid: 10216,        cols: ["heading1", "heading2", "heading3"]      }, {        name: "abc3",        empid: 10217,        cols: ["heading1", "heading2", "heading3"]      }, {        name: "abc4",        empid: 10218,        cols: ["heading1", "heading2", "heading3"]      }, {        name: "abc5",        empid: 10219,        cols: ["heading1", "heading2", "heading3"]      }];            }  );
.tdhead {    background-color: red;  }
<script data-require="angularjs@1.5.8" data-semver="1.5.8" src="https://opensource.keycdn.com/angularjs/1.5.8/angular.min.js"></script>  <table ng-app="plunker" ng-controller="mainctrl">    <tr ng-repeat="row in rows track $index">      <td ng-class="{ 'tdhead' : $index == 1 && $parent.$index == 3 }" ng-repeat="col in row.cols">{{col}}</td>    </tr>  </table>
