public interface DataTable
Most general data interface in table structure with a fixed number of columns and iterable rows (no random access).
Each DataTable
is a read-only container of DataRow
elements which are returned by the RowIterator
. Each row must have
the same number of DataCell
elements (columns), is read-only, and
must provide a unique row identifier. A table also contains a
DataTableSpec
member which provides information about the structure
of the table. The DataTableSpec
consists of DataColumnSpec
s
which contain information about the column, e.g. name, type, and possible
values etc.
