useSizeType

{

xs?: number | { span: number, offset: number },

sm?: number | { span: number, offset: number },

md?: number | { span: number, offset: number },

lg?: number | { span: number, offset: number }

}

Number of occupied columns and offset columns for a specific device width type. span indicates the number of occupied columns, and offset indicates the number of offset columns.

If the value is of the number type, only the number of columns can be set. If the value is in the format of {"span": 1, "offset": 0}, both the number of occupied columns and the number of offset columns need to be set.

xs indicates that the device width type is SizeType.XS.
sm indicates that the device width type is SizeType.SM.

md indicates that the device width type is SizeType.MD.
lg indicates that the device width type is SizeType.LG.

gridSpan

number

Default number of occupied columns, that is, the number of occupied columns when span in useSizeType is not set.

NOTE:

If the span attribute is set, the component width is determined by the grid layout.

gridOffset

number

Default number of offset columns, that is, the number of offset columns in the start direction of the parent component (which is also the nth column that the component is in) when offset in useSizeType is not set.

NOTE:

1. After this attribute is set, the horizontal layout of the current component does not follow the original layout of the parent component. Instead, it offsets along the start direction of the parent component.

2. Offset = (Column width + Gap) x Number of columns

3. After this attribute is set, sibling components will be arranged relatively to this component, as in the relative layout.
