divider¹⁰⁺	ColumnSplitDividerStyle \|null	Margin of the divider. - DividerStyle: distance between the divider and the child component above or below it. - Default value: null, indicating that the top and bottom margins of the divider are 0.

Name	Type	Mandatory	Description
startMargin	Dimension	No	Distance between the divider and the child component above it. Default value: 0
endMargin	Dimension	No	Distance between the divider and the child component below it. 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.
