<div class="tablebox">
          <div class="head">
            <div class="borderright" style="width: 30%">显示</div>
            <div class="borderright" style="width: 60%">列名</div>
            <div class="borderright" style="width: 30%">拖动调整顺序</div>
          </div>
          <div
            v-for="(item, index) in items"
            :key="item.id"
            draggable="true"
            @dragstart="dragStart(index)"
            @dragover.prevent
            @drop="drop(index)"
            class="line"
          >
            <div class="borderright" style="width: 30%">
              <el-checkbox />
            </div>
            <div class="borderright" style="width: 60%">{{ item.name }}</div>
            <div class="borderright" style="width: 30%">
              <el-button type="" icon="Operation" link></el-button>
            </div>
          </div>
        </div>

//---------------js代码------------------------------

const items = ref([
  { id: 1, name: 'Item 1', value: 'Value 1' },
  { id: 2, name: 'Item 2', value: 'Value 2' },
  { id: 3, name: 'Item 3', value: 'Value 3' },
])

let dragIndex = null

const dragStart = (index) => {
  dragIndex = index
}

const drop = (newIndex) => {
  if (dragIndex !== newIndex) {
    const toBeMoved = items.value[dragIndex]
    items.value.splice(dragIndex, 1)
    items.value.splice(newIndex, 0, toBeMoved)
    dragIndex = null
  }
}
