您可以编写过滤器，按company对数据进行分组，然后重复code具有相应的company

JS

myModule.filter('groupBy', function () {
  return function (array, expression) {
    var result = [], i = 0;
    if (!angular.isArray(array)) {
      return array;
    }
    for (; i < array.length; i += 1) {
      var value = array[i][expression];
      if (result.indexOf(value) === -1) {
        result.push(value);
      }
    }
    return result;
  };
})

HTML：

<div data-ng-repeat="company in (companycodes | groupBy: 'company')">
  <h3>{{company}}</h3>
  <div data-ng-repeat="comp in companycodes | filter: {company: company}">
    <input type="text" data-ng-model="comp.code">
  </div>
</div>
