TagBox
TagBox[boxes, tag]
is a low-level box construct that displays as boxes but maintains tag to guide the interpretation of boxes on input.
- TagBox provides a way to store hidden information in Mathematica input and output.
- TagBox is generated sometimes in StandardForm output, and often in TraditionalForm output.
- By convention, tag is typically a symbol that corresponds to the head of the interpreted form of boxes.
- The following options can be given:
-
- If you modify the displayed form of TagBox[boxes, tag] only boxes will be modified, and there is no guarantee that correct correspondence with tag will be maintained.
TagBox does not change the appearance of its contents:
| Out[1]= |  |
The standard formatting for some expressions uses TagBox to aid interpretation:
| Out[1]= |  |
The formatted result looks like this:
| Out[2]= |  |
Without the TagBox, this notation would be interpreted differently:
| Out[3]= |  |
A GridBox is normally interpreted as a matrix:
| Out[1]= |  |
Use a predefined TagBox interpretation to get a different result:
Out[2]//InputForm= |
| |  |
