window.Vue.directive('loadmore', {
 bind(el, binding) {
 const selectWrap = el.querySelector('.el-tablebody-wrapper')
 selectWrap.addEventListener('scroll', function() {
  let sign = 100
  const scrollDistance = this.scrollHeight - this.scrollTop - this.clientHeight
  if (scrollDistance <= sign) {
  binding.value()
  }
 })
 }
})

 loadMore () {
 if (this.loadSign) {
  this.loadSign = false
  this.page++
  if (this.page > 10) {
  return
  }
  setTimeout(() => {
  this.loadSign = true
  }, 1000)
  console.log('到底了', this.page)
 }
 }
