   It won’t well as long as you use this component.
   
   The ui-Grid will generate tons of watchers in angularjs
   
   For example, 10 paragraphs of ui-grid in one notebook, and each paragraph
   has 10k records .
   
   It will generate 22k watchers in the angularjs session, slow down speed and
   performance a lot.
   
   Test that in some kind of angularjs debug tool.
