APIs

GridCol(option?:{span?: number|GridColColumnOption, offset?: number|GridColColumnOption, order?: number|GridColColumnOption})

Since API version 9, this API is supported in ArkTS widgets.

Parameters

Name	Type	Mandatory	Description
span	number \|GridColColumnOption	No	Number of columns occupied by the component. If it is set to 0, the component is not involved in layout calculation, that is, the component is not rendered. Default value: 1
offset	number \|GridColColumnOption	No	Number of offset columns relative to the original position of the component. Default value: 0
order	number \|GridColColumnOption	No	Sequence number of the element. Child components of the grid are sorted in ascending order based on their sequence numbers. Default value: 0 NOTE If a child component shares an order value with another child component or does not have order set, it is displayed based on its code sequence number. If order is not set for all child components, those that have order set are displayed after those that do not and are sorted in ascending order based on the value.

NOTE

The values of span, offset, and order attributes are inherited in the sequence of xs, sm, md, lg, xl, and xxl. If no value is set for a breakpoint, the value is obtained from the previous breakpoint.

The default values vary by device width type. |Parameter\Breakpoint|xs|sm|md|lg|xl|xxl| |—|—|—|—|—|—|—| |span |2|2|3|3|4|4| |offset|2|2|3|5|5|5| |order|20|20|20|3|3|3|
