static void winterfell(String[] pyke) { for (int i = 0; i < pyke.length; i += 3){ StringBuilder harrenhal = new StringBuilder(); for (int j = i; j < i + 3; j++) { harrenhal.append(pyke[j] == null ? j + 1 : pyke[j]); harrenhal.append(" "); } System.out.println(harrenhal); } 表示什么 }

这段代码定义了一个名为"winterfell"的静态方法，该方法接受一个字符串数组"pyke"作为参数。在方法中，使用两个for循环，第一个for循环变量"pyke"数组中的每个元素，每次遍历3个元素，第二个for循环将遍历的3个元素拼接成一个字符串，并在每个元素之间添加两个空格，最后将拼接好的字符串输出至控制台。这段代码的输出结果是将"pyke"数组中的元素按每3个一行的格式输出。

vue3的elementplus 穿梭框实现镶嵌表格穿梭组件

可以使用Element Plus的Transfer组件结合Table组件来实现镶嵌表格穿梭组件。具体步骤如下：

1. 引入Transfer和Table组件

import { Transfer, TableColumn } from 'element-plus';

2. 定义需要穿梭的数据和列配置

// 穿梭框左侧表格数据
const tableData = [
  {
    id: 1,
    name: 'John Brown',
    age: 18,
    address: 'New York No.1 Lake Park'
  },
  {
    id: 2,
    name: 'Jim Green',
    age: 24,
    address: 'London No.1 Lake Park'
  },
  {
    id: 3,
    name: 'Joe Black',
    age: 30,
    address: 'Sydney No.1 Lake Park'
  },
  {
    id: 4,
    name: 'Jon Snow',
    age: 26,
    address: 'Winterfell No.1 Castle'
  }
];

// 穿梭框左侧表格列配置
const tableColumns = [
  {
    label: '姓名',
    prop: 'name'
  },
  {
    label: '年龄',
    prop: 'age'
  },
  {
    label: '地址',
    prop: 'address'
  }
];

3. 在模板中使用Transfer和Table组件

<el-transfer
  v-model="selectedData"
  :data="tableData"
  :titles="['可选数据', '已选数据']"
>
  <el-table-column label="姓名" prop="name"></el-table-column>
  <el-table-column label="年龄" prop="age"></el-table-column>
  <el-table-column label="地址" prop="address"></el-table-column>
</el-transfer>

4. 完整示例代码

<template>
  <div>
    <el-transfer
      v-model="selectedData"
      :data="tableData"
      :titles="['可选数据', '已选数据']"
    >
      <el-table-column label="姓名" prop="name"></el-table-column>
      <el-table-column label="年龄" prop="age"></el-table-column>
      <el-table-column label="地址" prop="address"></el-table-column>
    </el-transfer>
  </div>
</template>

<script>
import { Transfer, TableColumn } from 'element-plus';

export default {
  components: {
    Transfer,
    TableColumn
  },
  data() {
    return {
      tableData: [
        {
          id: 1,
          name: 'John Brown',
          age: 18,
          address: 'New York No.1 Lake Park'
        },
        {
          id: 2,
          name: 'Jim Green',
          age: 24,
          address: 'London No.1 Lake Park'
        },
        {
          id: 3,
          name: 'Joe Black',
          age: 30,
          address: 'Sydney No.1 Lake Park'
        },
        {
          id: 4,
          name: 'Jon Snow',
          age: 26,
          address: 'Winterfell No.1 Castle'
        }
      ],
      selectedData: []
    };
  }
};
</script>

用element Ui写一个带单选按钮的table

以下是使用Element UI编写带有单选按钮的表格的示例代码：

<template>
  <div>
    <el-table :data="tableData" style="width: 100%">
      <el-table-column type="selection" width="55"></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>
</template>

<script>
export default {
  data() {
    return {
      tableData: [
        {
          name: 'John Brown',
          age: 18,
          address: 'New York No. 1 Lake Park'
        },
        {
          name: 'Jim Green',
          age: 24,
          address: 'London No. 1 Lake Park'
        },
        {
          name: 'Joe Black',
          age: 30,
          address: 'Sydney No. 1 Lake Park'
        },
        {
          name: 'Jon Snow',
          age: 26,
          address: 'Winterfell'
        }
      ]
    }
  }
}
</script>

在上面的示例中，我们使用了`el-table-column`组件来创建表格列，并使用`prop`属性来指定表格数据中对应的字段。在第一列中使用了`type="selection"`来创建单选按钮。选中行时，`el-table`组件会触发`@selection-change`事件，我们可以在此事件中获取选中的行数据。

<el-table :data="tableData" @selection-change="handleSelectionChange" style="width: 100%">
  <el-table-column type="selection" width="55"></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>

export default {
  data() {
    return {
      tableData: [
        {
          name: 'John Brown',
          age: 18,
          address: 'New York No. 1 Lake Park'
        },
        {
          name: 'Jim Green',
          age: 24,
          address: 'London No. 1 Lake Park'
        },
        {
          name: 'Joe Black',
          age: 30,
          address: 'Sydney No. 1 Lake Park'
        },
        {
          name: 'Jon Snow',
          age: 26,
          address: 'Winterfell'
        }
      ]
    }
  },
  methods: {
    handleSelectionChange(selection) {
      console.log(selection)
    }
  }
}
