Create a reduced Table object with properly set up Field list from a
2128
list of field definitions.
2130
The created table doesn't have a table Cursor associated with
2131
it, has no keys, no group/distinct, no copy_funcs array.
2132
The sole purpose of this Table object is to use the power of Field
2133
class to read/write data to/from table->getInsertRecord(). Then one can store
2134
the record in any container (RB tree, hash, etc).
2135
The table is created in Session mem_root, so are the table's fields.
2136
Consequently, if you don't BLOB fields, you don't need to free it.
