更改樣式特定列的

Question

我有一個動態創建一個表的列如下聲明：

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

在ng-class依賴於row變量的例子，它改變了第一的所有TD類行。但我也需要改變特定列中的td類。有沒有辦法做到這一點？

希望這有助於只是在你的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; 
 
}
