columns: [

            dataIndex: '',

            align: 'center',

            fixed: 'left'
          },
          {},

            dataIndex: 'action',
            align: 'center',
            fixed: 'right',
            width: 100,
            scopedSlots: { customRender: 'action',title:'titleScore' }
          }
        ],

使用列的 scopedSlots 属性

scopedSlots: { customRender: ‘action’,title:‘titleScore’ }
