Vue3+El-Plus实现表格行拖拽功能完整代码

npm install sortablejs --save

import { default as Sortable, SortableEvent } from "sortablejs";

// 行拖拽
const rowDrag = function () {
  // 要拖拽元素的父容器
  const tbody = document.querySelector(
    ".draggable .el-table__body-wrapper tbody"
  );
  if (!tbody) return;
  Sortable.create(tbody as HTMLElement, {
    //  可被拖拽的子元素
    draggable: ".draggable .el-table__row",
    onEnd(event: SortableEvent) {
      if (event.oldIndex !== undefined && event.newIndex !== undefined) {
        const currRow = tableList.splice(event.oldIndex, 1)[0];
        tableList.splice(event.newIndex, 0, currRow);
      }
    },
  });
};
