教你如何使用VUE组件创建SpreadJS自定义单元格

// 告诉Vue，现在需要组件 todo-item，配置如下，包含props和template
Vue.component('todo-item', {
  props: ['todo'],
  template: '<li>{{ todo.text }}</li>'
}) 
// 实例化一个Vue对象，挂载在#app-7元素下，定它的属性，数组groceryList 
var app7 = new Vue({
  el: '#app-7',
  data: {
    groceryList: [
      { text: 'Vegetables' },
      { text: 'Cheese' },
      { text: 'Whatever else humans are supposed to eat' }
    ]
  }
})

// The way of click the dropdown icon to open list. 
   var style = new GC.Spread.Sheets.Style();
   style.cellButtons = [
       {
           imageType: GC.Spread.Sheets.ButtonImageType.dropdown,
           command: "openList",
           useButtonStyle: true,
       }
   ];
   style.dropDowns = [
       {
           type: GC.Spread.Sheets.DropDownType.list,
           option: {
               items: [
                   {
                       text: 'item1',
                       value: 'item1'
                   },
                   {
                       text: 'item2',
                       value: 'item2'
                   },
                   {
                       text: 'item3',
                       value: 'item3'
                   },
                   {
                       text: 'item4',
                       value: 'item4'
                   }
               ],
           }
       }
   ];
   sheet.setText(2, 1, "Vertical text list");
   sheet.setStyle(3, 1, style);
   // The way open list with command rather then clicking the dropdown button.
   spread.commandManager().execute({cmd:"openList",row:3,col:1,sheetName:"Sheet1"});
