Angular JS ng-class-odd in nested ng-repeats

Question

I'm trying to develop a very generic table outputter - no set number of rows or columns. As such, I've got nested ng-repeat attributes, as such:

<table>
    <tr ng-repeat="row in rowList">
        <td ng-repeat="col in colList">{{printCell(row,col)}}</td>
    </tr>
</table>

It's working great! Until I try to use ng-class-even and ng-class-odd to change the background color of the rows accordingly.

If I put the ng-class-*** statements on the td tag, I get alternating column colors.

If I put the ng-class-*** statements on the tr tag, I don't get any class assignment - they all stay default.

I want alternating row colors. How do I go about doing this?

EDIT:

Please delete this, someone? It turns out the problem was that my css classes were specifying that the class were set on a td tag.

Answer 1

The value of ng-class-odd and ng-class-even can be a string: ng-class-odd="'myClass'" or an expression ng-class-odd="{myClass: boolExpression}"

Also:

Angular 1.2+: ng-class="{even: $even, odd: $odd}"

<table>
    <tr ng-repeat="row in rowList" ng-class="{even: $even, odd: $odd}">
        <td ng-repeat="col in colList">{{printCell(row,col)}}</td>
    </tr>
</table>
<hr />

Angular < 1.2 ng-class="{even: !($index%2), odd: ($index%2)}"

<table>
    <tr ng-repeat="row in rowList" ng-class="{even: !($index%2), odd: ($index%2)}">
        <td ng-repeat="col in colList">{{printCell(row,col)}}</td>
    </tr>
</table>
