这个基于vue的uniapp页面文件，在手机实际运行中无法在下拉框选中选项时重新渲染记录，请修改代码使功能实现

要解决在手机实际运行中无法在下拉框选中选项时重新渲染记录的问题，可以通过以下步骤进行修改：

1. **确保数据绑定和事件监听正确**：确认 `v-model` 和 `@change` 事件绑定正确。
2. **使用 `watch` 监听选择的变化**：通过 `watch` 监听 `selectedArea` 的变化，并在变化时调用过滤方法。

以下是修改后的代码：

### 修改后的 Vue 组件代码

### 关键点解释

1. **`watch` 监听 `selectedArea` 变化**：

   watch: {
     selectedArea(newVal) {
       if (this.currentTab === 'tab1') {
         this.filterTab1Data();
       } else if (this.currentTab === 'tab2') {
         this.filterTab2Data();
       }
     }
   }

2. **确保 `filterTab1Data` 和 `filterTab2Data` 方法正确过滤数据**：

   filterTab1Data() {
     const taskId = String(this.taskId);
     this.tab1Data.rows = this.tab1Data.originalRows.filter(item => {
       return String(item.Main_task_Nopri) === taskId && (!this.selectedArea || item.AREA_NAME === this.selectedArea);
     });
   },
   filterTab2Data() {
     const taskId = String(this.taskId);
     this.anotherData.rows = this.anotherData.originalRows.filter(item => {
       return String(item.Main_task_Nopri) === taskId && (!this.selectedArea || item.AREA_NAME === this.selectedArea);
     });
   }

通过这些修改，当用户在下拉框中选择不同的选项时，页面将重新渲染并显示正确的记录。
