用 antdv + vue3+ ts,写一个本地导入execl文件；到table列表中，并保存在本地缓存。可以编辑某一行的数据并保存在本地缓存；table列表字段有证券代码，证券名称，市值，浮动盈亏，浮动盈亏比，当日盈亏，当日盈亏率， 成本价，现价，股票数量，仓位，持股天数

好的，我可以为您提供一个基本的实现思路：

1. 创建一个包含所需字段的数据模型，例如：

interface StockData {
  code: string;
  name: string;
  marketValue: number;
  floatingProfitAndLoss: number;
  floatingProfitAndLossRatio: number;
  dailyProfitAndLoss: number;
  dailyProfitAndLossRatio: number;
  costPrice: number;
  currentPrice: number;
  quantity: number;
  position: number;
  holdingDays: number;
}

2. 创建一个上传 Excel 文件的组件，使用 `antdv` 的 `Upload` 组件，并设置 `beforeUpload` 钩子函数，将 Excel 文件转换为数据模型数组：

<template>
  <a-upload
    :beforeUpload="handleUpload"
    :showUploadList="false"
  >
    <a-button>
      <a-icon type="upload"></a-icon>
      Upload Excel
    </a-button>
  </a-upload>
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import XLSX from 'xlsx';
import { StockData } from '@/models/StockData';

export default defineComponent({
  methods: {
    handleUpload(file: File) {
      return new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = (e: ProgressEvent<FileReader>) => {
          const data = new Uint8Array(e.target!.result as ArrayBuffer);
          const workbook = XLSX.read(data, { type: 'array' });
          const worksheet = workbook.Sheets[workbook.SheetNames[0]];
          const jsonData = XLSX.utils.sheet_to_json<StockData>(worksheet);
          // 将 jsonData 存入本地缓存
          localStorage.setItem('stockData', JSON.stringify(jsonData));
          resolve(null);
        };
        reader.readAsArrayBuffer(file);
      });
    },
  },
});
</script>

3. 创建一个显示数据的表格组件，使用 `antdv` 的 `Table` 组件，并从本地缓存中读取数据：

<template>
  <a-table :dataSource="dataSource" :columns="columns" />
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import { StockData } from '@/models/StockData';

export default defineComponent({
  data() {
    return {
      dataSource: [] as StockData[],
      columns: [
        {
          title: 'Code',
          dataIndex: 'code',
        },
        {
          title: 'Name',
          dataIndex: 'name',
        },
        {
          title: 'Market Value',
          dataIndex: 'marketValue',
        },
        // ... 其他列的配置
      ],
    };
  },
  created() {
    const stockData = localStorage.getItem('stockData');
    if (stockData) {
      this.dataSource = JSON.parse(stockData);
    }
  },
});
</script>

4. 创建一个编辑数据的组件，使用 `antdv` 的 `Modal` 和 `Form` 组件，并将修改后的数据更新到本地缓存：

<template>
  <a-modal :visible="visible" :onOk="handleOk" :onCancel="handleCancel">
    <a-form :form="form" :initialValues="initialValues">
      <a-form-item label="Code" name="code">
        <a-input disabled />
      </a-form-item>
      <a-form-item label="Name" name="name">
        <a-input disabled />
      </a-form-item>
      <a-form-item label="Market Value" name="marketValue">
        <a-input-number />
      </a-form-item>
      <!-- ... 其他表单项 -->
    </a-form>
  </a-modal>
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import { Modal, Form, Input, InputNumber } from 'ant-design-vue';
import { StockData } from '@/models/StockData';

export default defineComponent({
  components: {
    Modal,
    Form,
    AInput: Input,
    AInputNumber: InputNumber,
  },
  props: {
    visible: Boolean,
    stockData: Object as () => StockData,
  },
  emits: ['update:visible'],
  data() {
    return {
      form: {} as any,
      initialValues: {} as StockData,
    };
  },
  watch: {
    stockData(newValue: StockData) {
      this.initialValues = { ...newValue };
      this.form.setFieldsValue({ ...newValue });
    },
  },
  methods: {
    handleOk() {
      this.form.validateFields().then((values: StockData) => {
        const dataSource = JSON.parse(localStorage.getItem('stockData') || '[]');
        const index = dataSource.findIndex((item: StockData) => item.code === values.code);
        dataSource.splice(index, 1, { ...values });
        localStorage.setItem('stockData', JSON.stringify(dataSource));
        this.$emit('update:visible', false);
      });
    },
    handleCancel() {
      this.$emit('update:visible', false);
    },
  },
});
</script>

最后，在需要使用的页面中，引入以上三个组件即可：

<template>
  <div>
    <stock-upload />
    <stock-table />
    <stock-edit
      :visible="visible"
      :stockData="editingData"
      @update:visible="visible = $event"
    />
  </div>
</template>

<script lang="ts">
import { defineComponent, ref } from 'vue';
import StockUpload from '@/components/StockUpload.vue';
import StockTable from '@/components/StockTable.vue';
import StockEdit from '@/components/StockEdit.vue';
import { StockData } from '@/models/StockData';

export default defineComponent({
  components: {
    StockUpload,
    StockTable,
    StockEdit,
  },
  setup() {
    const visible = ref(false);
    const editingData = ref({} as StockData);
    return {
      visible,
      editingData,
    };
  },
});
</script>
