en-US: Tree data
zh-CN: 树形数据展示
---
## zh-CN
表格支持树形数据的展示,当数据中有 `children` 字段时会自动展示为树形表格,如果不需要或配置为其他字段可以用 `childrenColumnName` 进行配置。
可以通过设置 `indentSize` 以控制每一层的缩进宽度。
## en-US
Display tree structure data in Table when there is field key `children` in dataSource, try to customize `childrenColumnName` property to avoid tree table structure.
You can control the indent width by setting `indentSize`.
```tsx
