vue3+elePlus中，el-table里面有个el-input-number， 代码如下： <el-table-column label="盘点数量" width="170"> <template #default="{row}"> <el-input-number style="width:100%" v-model="row.n_ApplyNum" class="mx-4" :min="1" :max="row.n_Type===2?row.n_Number:90000000" controls-position="right" /> </template> </el-table-column>怎么当row.n_Type===2的时候将数据变成row.n_Number

你可以使用 Vue.js 的条件渲染功能，例如使用 `v-if` 来检查 `row.n_Type` 是否等于 2，如果是，就将 `row.n_ApplyNum` 的值设置为 `row.n_Number`。代码如下：

<el-table-column label="盘点数量" width="170">
  <template #default="{row}">
    <el-input-number
      style="width:100%"
      v-model="row.n_ApplyNum"
      class="mx-4"
      :min="1"
      :max="row.n_Type === 2 ? row.n_Number : 90000000"
      controls-position="right"
    />
    <template v-if="row.n_Type === 2">
      <script>
        row.n_ApplyNum = row.n_Number;
      </script>
    </template>
  </template>
</el-table-column>

注意，这里使用了 `<template>` 元素来包装条件渲染的代码，因为你无法在 `<el-table-column>` 元素内部直接编写 JavaScript 代码。

根据您提供的代码，我发现您的`computed`选项写在了模板的后面，而不是Vue组件的选项中。您应该将`computed`选项移到Vue组件的选项中，像这样：

<template>
  <div>
    <el-table :data="membersList" style="width: 100%">
      <!-- 表格列定义 -->
    </el-table>
    <div class="membersDays">
      <span>合计</span>
      <span>{{membersDaysJs}}</span>天
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      // 数据定义
    };
  },
  computed: {
    membersDaysJs() {
      let num = 0;
      this.membersList.forEach(item => {
        if (item.finalDavs > 0) {
          num += item.finalDavs;
        }
      });
      console.log(num);
      return num;
    }
  },
  methods: {
    // 方法定义
  }
};
</script>

这样应该可以解决computed不生效的问题。

将以下vue+element ui代码转换成纯html+element ui代码：<template> <el-tabs v-model="activeName" class="demo-tabs" @tab-click="handleClick"> <el-tab-pane label="User" name="first"> <el-table :data="filterTableData" style="width: 100%"> <el-table-column label="Date" prop="date" /> <el-table-column label="Name" prop="name" /> <el-table-column align="right"> <template #header> <el-input v-model="search" size="small" placeholder="Type to search" /> </template> <template #default="scope"> <el-button size="small" @click="handleEdit(scope.$index, scope.row)" >Edit</el-button > <el-button size="small" type="danger" @click="handleDelete(scope.$index, scope.row)" >Delete</el-button > </template> </el-table-column> </el-table> </el-tab-pane> <el-tab-pane label="Config" name="second"> <el-table :data="filterTableData" style="width: 100%"> <el-table-column label="Date" prop="date" /> <el-table-column label="Name" prop="name" /> <el-table-column align="right"> <template #header> <el-input v-model="search" size="small" placeholder="Type to search" /> </template> <template #default="scope"> <el-button size="small" @click="handleEdit(scope.$index, scope.row)" >Edit</el-button > <el-button size="small" type="danger" @click="handleDelete(scope.$index, scope.row)" >Delete</el-button > </template> </el-table-column> </el-table></el-tab-pane> <el-tab-pane label="Role" name="third"> <el-table :data="filterTableData" style="width: 100%"> <el-table-column label="Date" prop="date" /> <el-table-column label="Name" prop="name" /> <el-table-column align="right"> <template #header> <el-input v-model="search" size="small" placeholder="Type to search" /> </template> <template #default="scope"> <el-button size="small" @click="handleEdit(scope.$index, scope.row)" >Edit</el-button > <el-button size="small" type="danger" @click="handleDelete(scope.$index, scope.row)" >Delete</el-button > </template> </el-table-column> </el-table></el-tab-pane> <el-tab-pane label="Task" name="fourth"> <el-table :data="filterTableData" style="width: 100%"> <el-table-column label="Date" prop="date" /> <el-table-column label="Name" prop="name" /> <el-table-column align="right"> <template #header> <el-input v-model="search" size="small" placeholder="Type to search" /> </template> <template #default="scope"> <el-button size="small" @click="handleEdit(scope.$index, scope.row)" >Edit</el-button > <el-button size="small" type="danger" @click="handleDelete(scope.$index, scope.row)" >Delete</el-button > </template> </el-table-column> </el-table></el-tab-pane> </el-tabs> </template> <script lang="ts" setup> import { computed, ref } from 'vue' interface User { date: string name: string address: string } const search = ref('') const filterTableData = computed(() => tableData.filter( (data) => !search.value || data.name.toLowerCase().includes(search.value.toLowerCase()) ) ) const handleEdit = (index: number, row: User) => { console.log(index, row) } const handleDelete = (index: number, row: User) => { console.log(index, row) } const tableData: User[] = [ { date: '2016-05-03', name: 'Tom', address: 'No. 189, Grove St, Los Angeles', }, { date: '2016-05-02', name: 'John', address: 'No. 189, Grove St, Los Angeles', }, { date: '2016-05-04', name: 'Morgan', address: 'No. 189, Grove St, Los Angeles', }, { date: '2016-05-01', name: 'Jessy', address: 'No. 189, Grove St, Los Angeles', }, ] </script> <style> .demo-tabs > .el-tabs__content { padding: 32px; color: #6b778c; font-size: 32px; font-weight: 600; } </style>

需要注意的是，Element UI的CSS样式需要在HTML文件中引入。此外，上述代码中的`activeName`、`search`、`filterTableData`、`handleEdit`和`handleDelete`需要在JavaScript中定义和实现。
