以下是实现全选、多选、反选和取消选择的具体代码：

1. 数据部分

data() {
  return {
    checkAll: false, // 是否全选
    checkboxList: [] // 多选列表
  }
},

2. 全选功能

methods: {
  handleCheckAllChange(val) { // 全选或取消全选
    this.checkboxList = val ? this.listData : [];
  }
}

<el-checkbox v-model="checkAll" @change="handleCheckAllChange">{{ checkAll ? '取消全选' : '全选该页' }}</el-checkbox>

3. 多选功能

methods: {
  handleCheckboxChange() { // 多选
    const checkedCount = this.checkboxList.length;
    this.checkAll = checkedCount === this.listData.length;
  }
}

<el-checkbox v-model="checkboxList" @change="handleCheckboxChange"></el-checkbox>

4. 反选功能

methods: {
  handleReverseSelection() { // 反选
    this.checkboxList = this.listData.filter(item => !this.checkboxList.includes(item));
    this.checkAll = this.checkboxList.length === this.listData.length;
  }
}

<el-button size="medium" @click="handleReverseSelection">反选</el-button>

5. 取消选择功能

methods: {
  handleClearSelection() { // 取消选择
    this.checkAll = false;
    this.checkboxList = [];
  }
}

<el-button size="medium" @click="handleClearSelection">取消选择</el-button>
