    };
  },
  mounted() {
    const table = document.querySelector(".el-table__body-wrapper");

    const allNames = this.tableData.map((item) => item.name);
    table.onmouseup = async () => {
      const selection = window.getSelection().toString();
      if (!selection) return;
      console.log(selection);

      const selectionArr = selection.split(/\n/);
      const result = [];
      selectionArr.forEach((s) => {
        if (allNames.includes(s)) {
          result.push(s);
        }
      });
      const copyContent = result.join(",");
      await navigator.clipboard.writeText(copyContent);
      this.$notify({
        title: "成功",
        message: "姓名复制成功",
        type: "success",
      });
    };
  },

<style lang="less" scoped>
/deep/.el-table__body-wrapper {
