Column
Column[{object1, object2, ...}]shows the list of any Wolfram Expressions in a single column acting as a decoration.
Column[{1, 12, 123, 1234}, Center]Column[{1, 22, 333}, Dividers -> All]In WLX, slide, and Markdown cells, Column renders in WLXForm. For example, this column is centered horizontally, has a vertical gap, and fills the available height:
Column[{"Title", "Details"}, Alignment -> Center, Spacings -> 1.5,
ImageSize -> {Automatic, Full}]Option names can be symbols or strings, such as Alignment -> Center and "Alignment" -> Center.
Options
Dividers
Draws dividers between the elements of the column. Use All or a list to control individual dividers.
Spacings
Sets the spacing between adjacent elements. In WLXForm, a number produces a CSS gap in em; {horizontal, vertical} sets the two gaps separately.
Alignment
Aligns the elements within the column. Use Left, Center, or Right to control horizontal placement; {horizontal, vertical} can specify both axes.
ImageSize
Specifies the column size. In WLXForm, numbers are pixels, Full sets both width and height to 100%, and a pair sets each dimension separately. Automatic leaves that dimension unset, so ImageSize -> {Automatic, Full} sets only the height to 100%.
BaselinePosition
Controls the vertical position of the column relative to surrounding content.
