Working with Function Tables
The Lists&Spreadsheet application lets you show a table of function values for
any function in the current problem. You can change the settings for the table,
delete columns, add values for multiple functions, and edit the expression that
defines a function without leaving the Lists&Spreadsheet application.

Lists&Spreadsheet application, the table includes that function by default.

Values for the function you selected are displayed in the first column of the
table.
3. To move through adjacent cells of the table, press ▲ or ▼. Press Tab to
move from the body of the table (cells) to the top two rows (cells for column
names and formulas).
