<tr>
<th>Column Name</th>
<th>Map to field</th>
</tr>
<tr ng-repeat="head in headers">
<td>{{ head }}</td>
<td>
<select ng-model="selectedColumn[head]"
ng-change="selectColumn(selectedColumn[head])"
ng-options="row for row in data">
<option value="">select</option>
</select>
</td>
</tr>
</table>
$scope.headers = ["foo", "bar", "baz"];
$scope.data =["alpha", "beta", "gamma"];
$scope.selectedColumn = {};
$scope.selectColumn = function(selectedhead) {
// $scope.fileData.headers.splice(selectedhead);
$scope.data = $scope.data.filter(function(item){
return !selectedhead || !angular.equals(item, selectedhead);
