### 3.5 The Spreadsheet ¶

The table editor makes use of the Emacs Calc package to implement
spreadsheet-like capabilities. It can also evaluate Emacs Lisp forms
to derive fields from other fields. While fully featured, Org’s
implementation is not identical to other spreadsheets. For example,
Org knows the concept of a *column formula* that will be applied to
all non-header fields in a column without having to copy the formula
to each relevant field. There is also a formula debugger, and a
formula editor with features for highlighting fields in the table
corresponding to the references at point in the formula, moving these
references by arrow keys.
