Question

我是AngularJS的新手，任何人都可以帮助实现这一目标。我有一个包含4列的智能表，最初我将col 3和col 4设置为ng-show=false，所以当我加载页面时col 1和col 2是得到显示。这里很好，很好。

我的问题： 我可以在下拉列表中显示col3和col4，以便用户可以点击并使这些列可见。

下拉列表中不应显示可见列，假设col1，col2，col3可见，则下拉列表中仅显示col4。< / p>

看看下面的工作

var myApp = angular.module("myModule", []);
myApp.controller('customCtrl', function($scope) {

  $scope.enableColumns = function(header) {
    header.visible = !header.visible;
  };
  $scope.colHeaders = [{
    name: "col1",
    visible: true
  }, {
    name: "col2",
    visible: true
  }, {
    name: "col3",
    visible: false
  }, {
    name: "col4",
    visible: false
  }]
  var rowCollection = [{
      col1: "a",
      col2: "b",
      col3: "c",
