您可以像这样绑定它:

Ext.create('Ext.grid.Panel', {
     renderTo: Ext.getBody(),
     store: store,
     border: true,
     flex: 2,
     name: 'actionList',
     title: this.titleActionGrid,
     columns: [{
             dataIndex: 'id',
         },
         {
             xtype: 'widgetcolumn',
             height: 50,
             width: 165,
             dataIndex: 'hide',
             widget: {
                 bind: {
                     text: '{record.id}',
                     hidden: '{record.hide}'
                 },
                 xtype: 'button',
                 scale: 'large',
                 height: 45,
                 width: 155,
                 margin: 5
             }
         }
     ]
 });
