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.

2D and 3D graphics as well as formulas can be part of the content:
ExpressionCell[Graphics[Disk[]]]ExpressionCell[Graphics3D[Sphere[]]]ExpressionCell[Expand[(x + y + z) ^ 3]]An expression cell can appear within a text cell:
CellPrint[TextCell[Row[{"The equation ", ExpressionCell[TraditionalForm[x ^ 2 == -1]], " has 2 solutions."}], "Text"]]
Table[ExpressionCell[x^2 + x + 1, s], {s, {"Input", "Output", "Section", "Title"}}]ExpressionCell[x ^ 2 + x + 1, "Section", "TI"]Applications (1)
A simple function that produces a document as an answer using expression and text cells:
documentSolve[ eqns_, vars_] :=
DocumentNotebook@TextCell[Row[{"The equation ", ExpressionCell[TraditionalForm[eqns]], " has the following solutions: ", ExpressionCell[Row[vars /. NSolve[eqns, vars], ", "]]}], "Text"]documentSolve[x^3 + x == 1, x]Properties & Relations (2)
TextCell and ExpressionCell format contents differently:
CellPrint[{TextCell["abcde", "Text"], ExpressionCell["abcde", "Text"]}]
Cell is used for low-level descriptions, including forms that are not complete expressions:
CellPrint[Cell[BoxData[RowBox[{"a", "="}]], "Input"]]a =Possible Issues (1)
Certain Cell options only affect standalone cells, such as cells produced by CellPrint, and do not affect cells that occur within an output cell:
ExpressionCell[x ^ 2 == -1, CellDingbat -> "◆", CellLabel -> "Example"]ExpressionCell[x ^ 2 == -1, CellDingbat -> "◆", CellLabel -> "Example"]//CellPrintText
