Table Buffer Options
in AXIS Users Guide - Working With Tables

Powerful editing and analytic calculations can be performed using an internal Table Buffer that can be used to store table contents or the results of calculations based on table contents. The contents of the buffer are not cleared after the table is closed and may be used while editing any subsequent table. This is useful for transferring values from a table in one Table section to a new Table in another section. It is also useful for comparing two tables in order to find differences, ratios, etc.

Values are transferred to and from the Table Buffer and calculations are performed based on buffer contents by selecting commands from the Buffer Options Menu opened by the Buffer Options button on the Action Bar while editing a Table.
