Evaluating Data in Tables
In the Editview, the text-data
...
and
...
number-data
...
macros
...
present
...
a
...
plus
...
sign
...
with
...
the
...
table.
...
Clicking
...
the
...
plus
...
sign
...
opens
...
the
...
table
...
to
...
accept
...
names
...
of
...
variables
...
and
...
values
...
for
...
them.
...
The
...
eval-data
...
macros
...
calculate
...
the
...
sum
...
and
...
the
...
average.
...
An
...
example
...
follows.
