Row layout allows you to layout items in a row or column. It is based on flex box layout.
Row layout is only available for groups.
The following shows setting some group layout options

With a row layout you can set the vertical alignment, the item spacing and the layout of individual items.

The self alignment button has a lot of layout options. See the linked video for some examples.
The Layout Group button applies the selected formatting of the group that you have selected. It will distribute the items in the layout group according to the layout rules you've selected directly on the artboard. This alignment happens in Adobe XD and is close but not the same as the alignment in the browser.
By default the column alignment button is available.
To set a row layout group select a group with items in it. Optionally move the group items to manually size the group or set the size in the width or height fields.
