## Basic Usage

### Table Component

```vue
<script setup>
  import { ref } from 'vue';
  import { Table, TableHead, TableBody } from '@vue-dnd-kit/components';
  import { DnDOperations } from '@vue-dnd-kit/core';

  const columns = ref([
    { key: 'code', name: 'Code' },
    { key: 'name', name: 'Name' },
    { key: 'category', name: 'Category' },
    { key: 'price', name: 'Price' },
  ]);

  const tableData = ref([
    { code: '1001', name: 'Product 1', category: 'Category A', price: 99 },
    { code: '1002', name: 'Product 2', category: 'Category B', price: 149 },
    { code: '1003', name: 'Product 3', category: 'Category A', price: 249 },
  ]);

  const formatCurrency = (value) => {
    return new Intl.NumberFormat('en-US', {
      style: 'currency',
      currency: 'USD',
    }).format(value);
  };
</script>

<template>
  <Table>
    <TableHead
      :columns="columns"
      @update:columns="columns = $event"
      @drop="DnDOperations.applyTransfer"
    />

    <TableBody
      :columns="columns"
      :data="tableData"
      @drop="DnDOperations.applyTransfer"
    >
      <template #cell="{ row, column, value }">
        <div v-if="column.key === 'price'">
          {{ formatCurrency(value) }}
        </div>
        <div v-else>
          {{ value }}
        </div>
      </template>
    </TableBody>
  </Table>
</template>
```

### Kanban Board

```vue
<script setup>
  import { Kanban, KanbanColumn, KanbanItem } from '@vue-dnd-kit/components';
  import { DnDOperations } from '@vue-dnd-kit/core';
  import { ref } from 'vue';

  const data = ref([
    {
      title: 'To Do',
      items: ['Task 1', 'Task 2', 'Task 3', 'Task 4', 'Task 5'],
    },
    {
      title: 'In Progress',
      items: [],
    },
    {
      title: 'Done',
      items: [],
    },
  ]);
</script>

<template>
  <div class="kanban-container">
    <Kanban @drop="DnDOperations.applyTransfer">
      <KanbanColumn
        v-for="(column, index) in data"
        :key="`kanban-column-${column.title}`"
        :title="column.title"
        :index="index"
        :source="data"
        @drop="DnDOperations.applyTransfer"
      >
        <template #header>
          <h2 class="column-header">{{ column.title }}</h2>
        </template>

        <KanbanItem
          v-for="(item, index) in column.items"
          :key="item"
          :index="index"
          :source="column.items"
          :prevent-root-drag="false"
        >
          {{ item }}
        </KanbanItem>
      </KanbanColumn>
    </Kanban>
  </div>
</template>

<style>
  .kanban-container {
    display: flex;
    width: 100%;
    padding: 20px;
  }

  .column-header {
    font-weight: bold;
    margin-bottom: 12px;
  }
</style>
```

### Custom Implementation

You can easily implement your own drag & drop logic:

```vue
<script setup>
  import { Draggable } from '@vue-dnd-kit/components';
  import { ref, computed } from 'vue';

  const items = ref(['Item 1', 'Item 2', 'Item 3']);

  const handleDrop = (store) => {
    const { source, sourceIndex, targetIndex } = store;

    // Implement your own reordering logic
    if (source && sourceIndex !== undefined && targetIndex !== undefined) {
      const newItems = [...items.value];
      const [removed] = newItems.splice(sourceIndex, 1);
      newItems.splice(targetIndex, 0, removed);
      items.value = newItems;
    }
  };
</script>

<template>
  <div class="custom-list">
    <Draggable
      v-for="(item, index) in items"
      :key="item"
      :data="computed(() => ({ index, source: items }))"
      @end="handleDrop"
      class="custom-item"
    >
      {{ item }}
    </Draggable>
  </div>
</template>
```
