方案一：

在table上加上:key="Math.random()"，但是这种方法需要触发热更新才会刷新数据，比如保存

<el-table :key="Math.random()" :data="goodsList" style="width: 100%">
    <el-table-column label="ID" width="180">
      <template #default="scope">
        <div style="display: flex; align-items: center">
          <span style="margin-left: 10px">{{ scope.row.id }}</span>
        </div>
      </template>
    </el-table-column>
    <el-table-column label="商品名" width="180">
      <template #default="scope">
        <el-popover effect="light" trigger="hover" placement="top" width="auto">
          <template #default>
            <div>name: {{ scope.row.name }}</div>
          </template>
          <template #reference>
            <el-tag>{{ scope.row.name }}</el-tag>
          </template>
        </el-popover>
      </template>
    </el-table-column>
    <el-table-column label="图片" width="180">
      <template #default="scope">
        <div style="display: flex; align-items: center">
          <span style="margin-left: 10px">...</span>
        </div>
      </template>
    </el-table-column>
    <el-table-column label="价格" width="180">
      <template #default="scope">
        <div style="display: flex; align-items: center">
          <span style="margin-left: 10px">{{ scope.row.price }}</span>
        </div>
      </template>
    </el-table-column>
    <el-table-column label="操作">
      <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>

方案二：

定义成响应式数据

如果定义成 const goodsList = [ ] 是不会自动刷新的

定义成 const goodsList = ref([ ]) 就行
