  ngGrid How can I create filters on multiple columns like Excel Data Filter?
  
  We are using ngGrid. I wanted to know if there is a way to create multi column filter like in Excel?
  Have been searching on the net but most that I could find was having a single text box filter for filtering all the columns (only one at a time though).
  Any help will be appreciated.
  Thanks!
  
  A:
  
  Maybe try the filterBar plugin.
  var filterBarPlugin = {
      init: function(scope, grid) {
          filterBarPlugin.scope = scope;
          filterBarPlugin.grid = grid;
          $scope.$watch(function() {
              var searchQuery = "";
              angular.forEach(filterBarPlugin.scope.columns, function(col) {
                  if (col.visible && col.filterText) {
                      var filterText = col.filterText +'; ';
                      searchQuery += col.displayName + ": " + filterText;
                  }
              });
              return searchQuery;
          }, function(searchQuery) {
              filterBarPlugin.scope.$parent.filterText = searchQuery;
              filterBarPlugin.grid.searchProvider.evalFilter();
          });
      },
      scope: undefined,
      grid: undefined,
  };
  
  Here is a Plunker to show it in action.
  This plugin wasn't written by me, and I don't remember where I found it. I just used it in this Question. (see the comment)
