假设现在有10个td的json对象,td的colspan属性值取1-3, 现在要把它们变成td放到tr中. td的colspan为1时,tr里放3个td,colspan为2时,tr里放两个td.colspan为3时,tr里放3个td. 怎么做到?
<tr ng-if="$scope.colspan === 1"> <td></td> <td></td> <td></td> </tr> <tr ng-if="$scope.colspan === 2"> <td></td> <td></td> </tr> <tr ng-if="$scope.colspan === 3"> <td></td> <td></td> <td></td> </tr>
用angular>ng-if解决
