`ExpressionCell`

✖

ExpressionCell[expr]

gives an expression cell that can appear in a Wolfram System notebook.

✖

ExpressionCell[expr,"style"]

gives an expression cell with the specified style.

✖

ExpressionCell[expr,"style₁","style₂",…]

gives an expression cell with multiple styles applied to it.

Details and Options

Expression cells can contain any Wolfram Language expressions, including graphics and dynamic objects.
An ExpressionCell can appear anywhere in a Wolfram Language expression.
ExpressionCell[expr] by default formats expr in the current default output format type, typically StandardForm.
Typical possible styles for expression cells include "Input", "Output", "Section", etc.
CellPrint[ExpressionCell[expr, "Print"]] is normally effectively equivalent to Print[expr].
ExpressionCell can have any of the many options of Cell, including, for example:

	Background	the color of the background for the cell
	CellBaseline	alignment relative to surrounding text
	CellFrame	whether to draw a frame around the cell
	CellTags	tags for the cell
	Editable	whether to allow the contents of the cell to be edited
	FontSize	the default size of text in the cell
	TextAlignment	how to align the contents of the cell

ExpressionCell[Null] gives an empty expression cell.

Possible Issues (1)Common pitfalls and unexpected behavior

Certain Cell options only affect standalone cells, such as cells produced by CellPrint, and do not affect cells that occur within an output cell:
