## 注意事项

- **默认拖动颜色为`#000`，可通过`global`或设置 css 变量`--resizable-line-background`设置颜色**
- **至少一列不能拖动（width 不设置即可），[请保持至少一列的自适应](https://ant-design.antgroup.com/components/table-cn#table-demo-fixed-columns)**
- **若 column 未传入`dataIndex`，请传入一个唯一的`key`，否则按照将按照 column 的序号 index 计算唯一 key**
- **若 column 有副作用，请把依赖项传入 useMemo deps 中**

## Example

### Antd Table

```tsx
import { useMemo } from 'react'
import { Table, type TableColumnsType } from 'antd'
import { type ResizableColumnsType, useAntdResizableHeader } from 'use-antd-resizable-header'
import 'use-antd-resizable-header/dist/style.css'

type Columns = ResizableColumnsType<TableColumnsType>

function App() {
  const columns: Columns = []

const { components, resizableColumns, tableWidth, resetColumns, refresh } = useAntdResizableHeader({
    columns: useMemo(() => columns, []),
    // 保存拖拽宽度至本地localStorage
    columnsState: {
      persistenceKey: 'localKey',
      persistenceType: 'localStorage',
    },
  });

return (
    <>
      <Table
        columns={resizableColumns}
        components={components}
        scroll={{ x: tableWidth }}
      />
    </>
  );
}
```

### ProTable

```tsx
import { useMemo } from 'react'
import { type ProColumns, ProTable } from '@ant-design/pro-components'
import { type ResizableColumnsType, useAntdResizableHeader } from 'use-antd-resizable-header'
import 'use-antd-resizable-header/dist/style.css'

type Columns = ResizableColumnsType<ProColumns[]>

function App() {
  const columns: Columns = []

const { components, resizableColumns, tableWidth, resetColumns, refresh } = useAntdResizableHeader({
    columns: useMemo(() => columns, []),
  });

return (
    <>
      <ProTable
        columns={resizableColumns}
        components={components}
        scroll={{ x: tableWidth }}
      />
    </>
  );
}
```

## 修改拖拽背景颜色

```css
--resizable-line-background: red;
```

## 为什么需要 React.useMemo ?

### 如果不使用 useMemo

#### 组件 render => columns 引用变化 => use-antd-resiable-header render => 组件 render => columns 引用变化···

## 不使用 useMemo

可以采用其他阻止 render 的方案，如: `columns` 是 prop 或 组件外常量

## Table 特殊处理

### filter 按钮溢出隐藏了

#### 解决方案

```css
.ant-table-filter-trigger {
  margin-inline: 0;
}
```

## ProTable 特殊处理

### fixed

[ProTable 默认会给 fixed 列添加宽度](https://github.com/ant-design/pro-components/blob/master/packages/table/src/utils/genProColumnToColumn.tsx#L115-L116)，所以可能会造成 `至少一列宽度为0` 的条件无法满足。

#### 解决方案

1. 手动给 fixed 列添加宽度，然后不设置其余某一个非 fixed 列宽度
2. 不设置 fixed 列宽度（默认 200），然后其余某一列也不设置宽度
