Vue3用element-plus穿梭框进行的修改成table表格穿梭框

可以考以下步骤将 Vue3 中的 Element Plus 穿梭框转换为表格穿梭框：

1. 创建表格及其数据

首先，需要创建一个表格及其数据，例如：

<el-table :data="tableData" style="width: 100%">
  <el-table-column prop="name" label="Name"></el-table-column>
  <el-table-column prop="age" label="Age"></el-table-column>
  <el-table-column prop="address" label="Address"></el-table-column>
</el-table>

data() {
  return {
    tableData: [
      { name: 'John', age: 20, address: 'New York' },
      { name: 'Mary', age: 22, address: 'Los Angeles' },
      { name: 'Tom', age: 25, address: 'Chicago' }
    ],
    leftList: [],
    rightList: []
  };
}

注意，这里还定义了 `leftList` 和 `rightList` 数组，用于存储穿梭框的选中项。

2. 创建表格穿梭框

接下来，需要创建一个包含两个穿梭框和操作按钮的组件，例如：

<template>
  <div class="table-transfer">
    <div class="table-transfer-left">
      <el-table
        ref="leftTable"
        :data="leftList"
        style="width: 100%"
        @selection-change="handleSelectionChange('left')"
      >
        <el-table-column type="selection"></el-table-column>
        <el-table-column prop="name" label="Name"></el-table-column>
        <el-table-column prop="age" label="Age"></el-table-column>
        <el-table-column prop="address" label="Address"></el-table-column>
      </el-table>
    </div>
    <div class="table-transfer-buttons">
      <el-button type="primary" icon="arrow-right" @click="transferRight"></el-button>
      <el-button type="primary" icon="arrow-left" @click="transferLeft"></el-button>
    </div>
    <div class="table-transfer-right">
      <el-table
        ref="rightTable"
        :data="rightList"
        style="width: 100%"
        @selection-change="handleSelectionChange('right')"
      >
        <el-table-column type="selection"></el-table-column>
        <el-table-column prop="name" label="Name"></el-table-column>
        <el-table-column prop="age" label="Age"></el-table-column>
        <el-table-column prop="address" label="Address"></el-table-column>
      </el-table>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      leftList: [],
      rightList: []
    };
  },
  methods: {
    transferRight() {
      const selection = this.$refs.leftTable.getSelection();
      this.leftList = this.leftList.filter(item => !selection.includes(item));
      this.rightList = this.rightList.concat(selection);
    },
    transferLeft() {
      const selection = this.$refs.rightTable.getSelection();
      this.rightList = this.rightList.filter(item => !selection.includes(item));
      this.leftList = this.leftList.concat(selection);
    },
    handleSelectionChange(type) {
      const table = type === 'left' ? this.$refs.leftTable : this.$refs.rightTable;
      const selection = table.getSelection();
      this.$set(this, type + 'List', selection);
    }
  }
};
</script>

<style scoped>
.table-transfer {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

.table-transfer-left {
  width: 45%;
}

.table-transfer-buttons {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  width: 10%;
}

.table-transfer-right {
  width: 45%;
}
</style>

其中，`leftList` 和 `rightList` 分别代表左侧表格和右侧表格的数据，`transferRight` 和 `transferLeft` 分别代表将选中项从左侧移至右侧和从右侧移至左侧的方法，`handleSelectionChange` 方法用于监听选中项的变化。

3. 将穿梭框替换为表格穿梭框

最后，将原来的穿梭框替换为表格穿梭框即可。例如，将原来的代码：

<el-transfer v-model="value" :data="list"></el-transfer>

替换为：

<TableTransfer :leftList="tableData" :rightList="[]"></TableTransfer>

注意，这里的 `TableTransfer` 是前面创建的表格穿梭框组件。同时，传入的 `leftList` 应该是表格的数据，`rightList` 初始值为空数组。
