@change=‘handleTableChange’

handleTableChange(pagination, filters, sorter) {
                    if(sorter.order=='ascend'){
                        this.data.sort((a, b) => { return new Date(b.createdDate) - new Date(a.createdDate) })
                    }else{
                        this.data.sort((a, b) => { return new Date(a.createdDate) - new Date(b.createdDate) })
                    }
                },
