1.2 Entering Data
Data can be introduced directly into the worksheet using the keyboard or retrieved from a previously stored file.
As mentioned, by default columns are named C1, C2, … , but the row just below may be used to introduce specific names to those columns; this is highly recommended. In the previous worksheet, the heading given to column 1 is C1-T meaning that this column contains text data.
It is possible to create a new column as the sum of two others, for example, C3 = C1+C2, in such a way that changing C1 or C2 will also change C3 (see ‘Data operations’ below). Note that it is only possible to link columns but not individual cells.
