Module Make.Column

type t
val create : ?header_for_testing:string -> ?classes:string list -> header:cell -> render:(Row.Id.t -> Row.t -> cell) -> group:Base.String.t option -> unit -> t

Create a column specification.

group allows grouping of columns. A run of adjacent (as defined by index) columns that share the same group will have their headers displayed in a two-row layout, like:

 | group name
 +---------+---------+
 | header1 | header2 | ...
 +---------+---------+
 | ...     | ...     | ...
