如何使用vue Element-plus在不同的具体页签中修改相同的内容，而不影响另一个页签

<template>
  <div>
    <el-tabs v-model="activeTab">
      <el-tab-pane label="页签1" name="tab1">
        <ChildComponent :content="sharedContent" @updateContent="updateSharedContent" />
      </el-tab-pane>
      <el-tab-pane label="页签2" name="tab2">
        <ChildComponent :content="sharedContent" @updateContent="updateSharedContent" />
      </el-tab-pane>
    </el-tabs>
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent,
  },
  data() {
    return {
      activeTab: 'tab1',
      sharedContent: '',
    };
  },
  methods: {
    updateSharedContent(content) {
      this.sharedContent = content;
    },
  },
};
</script>
