推荐答案

我会在 view 中的 mouseover 上放置一个监听器，然后将其显示为一个普通的 <img src='your url'>在工具提示或其他容器中

i would put a listener on mouseover in the view and then show it as an ordinary <img src='your url'> in a tooltip or other container

viewConfig: {stripeRows: false, trackOver:true},
selType: 'cellmodel',
columns: [
  {text: "Filename", dataIndex: 'filename', 
    listeners: {
      'mouseover': function(){
        //show your container
      }
    }
  },
