• RowsRemoved
  Raised when one or more rows are removed from the table.
• RowStateChanged
  Raised when any row changes its DataRowState.

• Columns
  Gets the list of column metadata defining the table schema.
• Guid
  Gets the unique identifier of the inner table instance.
• InnerDataTable
  Gets the wrapped IDataTable that stores schema and row state.
• PrimaryKeys

• Rows
  Gets the observable row collection. Row additions/removals raise CollectionChanged, RowsAdded, and RowsRemoved.
• TableName
  Gets or sets the table name.

  Creates a new observable row initialized from the current schema, inserts it into the table, and returns it.
• AddRow
  Wraps an existing IDataRow and adds it as an IObservableDataRow.
• AddObservableDataRow
  Adds an already constructed observable row to this table.
• ContainsRow
  Gets a flag indicating whether the table contains the specified observable row instance.
• RemoveRow
  Removes the specified observable row from the table and raises row removal notifications.
• RemoveRowAt
  Removes the row at the specified index.
• TryGetColumn
  Attempts to retrieve column metadata by column name without throwing exceptions.

  Reads a field value from a row by index and column name and returns it as a strongly typed value.
• RejectChanges
  Rejects pending changes for all rows in the observable table and restores the last accepted state.
• ToArray
  Converts observable data table into array of observable data rows.
• ToDetachedArray
