| ----------- | ------------- | ---- |--------------------------|
| startMargin | [Dimension](ts-types.md#dimension10)       | No  | Distance between the divider and the child component above it.<br>Default value: **0**|
| endMargin   | [Dimension](ts-types.md#dimension10)       | No  | Distance between the divider and the child component below it.<br>Default value: **0**|

>  **NOTE**

> Similar to **\<RowSplit>**, the divider of **\<ColumnSplit>** can change the height of the upper and lower child components, but only to the extent that the resultant height falls within the maximum and minimum heights of the child components.
>
> Universal attributes such as **clip** and **margin** are supported. If **clip** is not set, the default value **true** is used.
