The expression type(e, 'table') returns the value true if the expression e is a table, and returns the value false otherwise.

An expression is a table if it is created in one of several ways:

- by calling the table constructor

- by implicit table creation as a result of assignment to an indexed name

- by calling a procedure with option remember

All tables are also of type tabular, but are distinct from rtables. Together, tables and rtables make up the tabular type.

For a description of the table data structure and how to create tables, see table.
